Since this method will be used throughout and there will be more additions to this page as time goes on, the description of the method used to connect the wires is right here up front! I don't like Scotch locks for wire splice in. Even LeverLocks , which are very large (often too large for tight spaces), require you cut a wire or two. BOTH are bulky, often loosen over time and corrode. Soldering is best, but that is sometimes very difficult if not impossible. I often use the "tuck and roll" method (shown at right) which works good on smaller connectors with light gauge wires, but that's sometimes not practical with these tight mini connectors. Using, in the order of ease of use and durability: best is a safety pin leg (good for waterproof connectors like these), a leg from a diode/resistor, 1 inch length of 20-22 gauge bell wire (solid copper not strands) or a ceiling tile staple, one can make a "probe" that will slip into a connector from behind on the plug as shown. Grab a proper size gauge diode or safety pin and cut off a leg leaving enough to re-use the diode. Solder your lead onto one leg end leaving about 1/2" or more of a leg free. Put on some heat shrink and lube it good with bulb grease and insert tightly into the back of the plug so that it makes good contact with the connector of the needed wire. After "smoke" testing, zip tie or tape it to the existing wire and zip tie to the harness too for good strain relief. (if doing a waterproof connector, you can add a dollop of hot glue or bulb grease before tying off). This way, if you ever need to disconnect that which you have connected, simply cut the zip ties and "unplug" your piggy back EZ Splice. Works great and it's easy. One helpful thing here is to use a "Helping Hand" soldering stand available at Radio Shack to help make a neat solder of the wire to the leg/pin. I've been using this method for 20 years in inclement weather of all sorts including snow, salt and mud (on my quads) and have never lost a connection. To the purist. A connector is a device which slides one metal "blade" over another metal "blade" to make a connection. We are merely doing exactly the same thing. There are commercial versions of this here: *click me*
This outlet/inlet supplies power for my heated gear and doubles as a receiver from my battery maintainer. Pulled the bag and used a 1/4" coaxial connection between the bag and body so that I can unplug it should I ever need to remove the bag again. Drilled one hole and hid all the wiring under the seat coming from the battery directly using the BuRP supplied fused SAE plug in the frunk. I merely changed to a 10 amp fuse in the factory pigtail. This is Warm n Safe's outlet module.
load new routes (trips) on a 57 Nüvi from the sd, insert the card and
reboot the GPS (it takes some time).
I could not afford nor did I want to spend upward of $700 for a zumo. I obtain inexpensive Nüvi off eBay for use on my bikes. For weather proofing, just carry some sandwich bags to cover it. It's still visible and workable. Too, even if it does get ruined wet, you're only out under $50.
RAM stuff is just too bulky. More suited for mounts on a dually truck! I am a minimalist so I went my own route. I bought a Garmin Nüvi 57 LM for $60 on eBay. I did utilize RAM's Garmin Nüvi 57LM cradle ($12 eBay). I drilled and tapped 2 holes in my bar clamp for #10 screws. I bent a hunk of 14 gauge light steel at a 45° angle and mounted it to my cradle and clamp. The screws need to be hex head to both the clamp & cradle so that one can tighten them in the narrow space. Painted black with DupliColor truck bed liner it blends right fine with F3T textured black motif. Power comes up from the OEM GPS System power (which is found behind the left rear lateral body pane near the GPS audio in) using one of these GPS circuit connectors. I extended the GPS OEM power connector (goes live with the key and dies 10 seconds after key off) to up to the front under the service panel where I put a "cigarette lighter" plug there to use the supplied power cable from Garmin threaded up through the button/key shroud. Minimal. The pic to the left shows the rider view and the full compliment of the Spyder dash is unobstructed. The pic to the right shows the mount. Click here to see a garage door opener mounted with magnet.
The F3-T has a radio. Included in the OEM wiring is a male 1/8" jack (like earbuds) to place into a 1/8" audio female plug. When the radio gets a signal from a GPS connected there it will mute the music and play the prompt from it ("Turn left at the traffic light"). Some GPS models have a headfone /audio out female but most do not and if they do, they are way above my pay grade. I use a Garmin 57 Nüvi which has none so I added an audio out to it by soldering on the clearly labeled board the RED to the speaker + (plus) and BLACK to the speaker -- (minus) from a cut off 1/8" headfone extension female end. To get inside a Nüvi take out the 4 #T5 Star screws then run a spudger or fingernail around the edge until the case pops open. Take care not to damage the ribbon cable. On my Nüvi 57 it was necessary to trim the plastic a little to make room for the pigtail. I hot glued the wire routed through the case so there would be good strain relief and a dollop for dust/water proof where it exits the case. Snap the case back together. It will fully snap shut once you replace the screws. I ran another 1/8" headfone extension cord (6 feet should do) from the bike's male GPS audio input (which is found behind the left rear lateral body panel) up to my Garmin mount and plugged its male into my 57's new female output pigtail. You must adjust the volume on your GPS to match that of the OEM radio so the prompts won't shout too loudly.
To activate it the first time, it may be necessary to switch your input to NAV and cause the GPS to sound. After that, it will work to mute any audio source (USB, line in, FM) for the GPS prompts. Click the pics for larger labeled images. The 57LMTraffic Nüvi sends a click about 2 seconds post prompt, but the 57LM Nüvi does not which is more pleasing.
[hint] the GPS input is a full compliment audio capable of playing a full audio source such as a cell phone or mp3 player*. If you have a cell phone that reads your text messages to you, use this input to mute the stereo and play your message as if it was a GPS prompt. This is an IDEAL way to use a music capable ZUMO! Set the input to NAV for full time audio using this input for the output of the ZUMO. * If you have a model that does not provide an audio in for prompts, Kennedy has an interface that will do it for you.
Or how I beat the CANbus

The OEM turn signals in the rear are incandescent and hopelessly dim. I wanted to add surface mount Ultra Bright LED lights (T3) in the guise of Feniex T3 Perimeter Mount LED (Amber) to supplement them. However, the CANbus is a pain in the BUS! When I first tried to put these extra T3 lights on, I just (foolishly) hooked them up straight to the signal wires on each side using the EZ-Splice method shown above. The T3s worked. but the bike went into rapid fire bulb out error. UGH! So now what? The lights draw about .3 AMPs which is likely too much for the CANbus circuit to not error. The idea struck me to insert a relay inline so the BUS would see very little draw ameliorating the difference between installed and not. The relay was small & meant for a computer, but it still drew too much current. I had one Radio Shack reed relay in my collection so I tried that... voilà! It worked! But I only had one. On the other side I tried a smaller computer relay and again voilà! I used the tail circuit (orange) to feed +12v to the extra LED reducing the load on the signal wire. The OEM signal +12v is fed to the relay coil and ground is ground. I purchased some 4 conductor wire at Lowes which had RED, BLACK, GREEN & WHITE wires. The pic illustrates which wires to where on the reed relay (eBay) and the arrows show it on the computer relay and if you need to know what the relay terminal numbers mean, look >here<. These relays can be found on eBay and @ Radio Shack. The T3 needs to be set to full bright on mode which times out in about 5 seconds but it works well for a signal. That mode is between strobe once then full (light just strobes as a signal so can't use) and constant on but dim (clearly unsatisfactory). How to for T3 surface program and wire at this video
SUPER BRIGHT SIGNAL LIGHTS
EZ Access to the interior of the light on F3-T
To access the signal wiring remove the four body clips under the bag lid AFTER having taped in place the metal tab as shown. Under the bag is a #20 torx which must be removed. You can then pull the tail light bag assembly apart and out (like opening a clam) to reveal the inner wiring. Put a 2x4 block to keep it open. This will give you access to the inner wiring without much work. Click the pics below for a larger view.
|The video at left shows my T3 signals, T3 strobe/flashing brake light, Custom Dynamics Knight Riderz 21 LED
top light bar and the tinted short bottom light bar. The four corners of my license plate frame
also has white but not so bright strobe lights which flash until I let off the brake pedal. |
The brake Feniex T3 Perimeter Mount LED (RED) strobes quickly once using a solid state 8 AMP brake light flasher module from Amazon which is barely the size of a quarter. It strobes quickly then goes to solid but..... because I have the T3 set to flash every three seconds the two units combined cause the T3 to strobe quickly once then flash every three seconds on/off until I let off the pedal. For this video, I have masked off the utlra bright flashing T3 brake light because it washed out all the others in the video. When viewed directly these T3 LEDs are remarkable. You can see the three LEDs through the tape. I ran into a bit of trouble with the CANbus with the long light bar. I had it feeding from the tail light ORANGE off the right tail light connector. When I put on the right signal, because I was feeding my T3 amber signal light from the tail ORANGE, the light bar exhibited some strange behavior. It would flicker, run only in one direction, flash just 3 of the LEDs and other goofy stuff. So, I set that light bar to run off the OEM GPS circuit and everything was then copacetic. .
|The video at the right shows my
cubby vent signals which act as both a
brighter indicator for the ryder as well as a visual signal to the
public as side signals. This is accomplished using set of 4"
from Amazon. Installation is straightforward. Attach the strips to the cubby
top along the inner edge and run the RED wire to the signal +12v and
the black to the signal ground. They reflect off the service cover
casting light outward to the driver next to you and the reflection
from the front fairing panel is visible as an indicator for the
ryder to see the signal is on. Some have complained that the OEM
indicators are too dim. $7 solution! |
||The video at the right shows my
$17 replacement for my gone bad $180 BuRP signature light. I fought
with BuRP for two years and they would not replace the defective LED
under Warranty. Installation for my version is simple. One can power
these lights with the OEM signature light circuit under the frunk liner and wire
them up just like the signature light to the OEM wires. The only
difference being that they must also get wired by their respective
yellow to the left and right
turn signals. They come on as white DRLs with the key and when a
turn signal is activated, they will switch to amber and sequentially
show the direction you will be turning. Costing 10 times less than
the signature light, I bought two sets which gives me two spare
lights just in case. I like them. Apply the 3M mounting tape
under the rim with the frunk lid open. Check the pics. I duct taped
the wires under the frunk liner as shown
installation video for the Signature light. Instead of just a
hole for the wire, I cut a slot in the plastic. |

The stock horn is one of those totally inadequate "gee, I'm sorry to bother you but beep ".. pieces of junk. I was always happy with my GL1800 horns and found a set (hi & lo) on eBay for $24! The harmonics produced with the stock horn and the GL horns is BLARING! The strobes fire for 15 seconds after the first BEEP! I've been running horny strobes for many years on all my bikes and never had a problem with any LEO. The horns and wiring are mounted behind the grille with sticky tape in that big cavern under the frunk.
The necessary wiring diagram is shown below for just adding horns or at the left using a standard Bosch auto relay, a time delay relay and an alternating strobe module for strobes. Because the OEM horn wire is always hot, the horn button completes the ground at the horn. We use that GROUND to switch our BOSCH relay at terminal 85. I powered it all directly from the battery lead supplied with the F3T. I replaced the 7.5 amp fuse in it with a 10 amp fuse which the wire gauge will easily handle. The LEDs I used were from an old set of remote programmable strobes but the module it came with didn't remember the setting after being unpowered so I just used the 4 LED lights with another alternating strobe module. I mounted the lights to the grille with the sticky back that comes on them and a zip tie through the screen and around the wire of each light. The end of the video below >CLICK<. shows the action. You can run very many strobe lights off any strobe module by using the same relay I used for my signals or the 10 amp version. You will need two relays for alternating. Circuit here:>click<.

For just adding horns
I bought and love an Ultimate Seat. In its slot I installed a Big Bike Parts 41-168A backrest anchored with screws as shown. I only used three parts as shown to mount it. I chose this backrest because it's low and easier to get a leg over than the taller ones. I have an Airhawk Cushion from 1998 which supplements on long rides (yes, it's 20 years old and still working great).. I use the method of running with the Airhawk for a coupla hours and then running without it for a coupla hours. I also run a full Merino sheep skin rug from New Zealand to ameliorate the seat's heat in the summer. I run both at the same time sometimes. To hold the Merino I simply sewed on paracord with monkey's fist knots to the back corners and capture them in the saddle bag lids outside of the gasket when I close them.
|What you will need obtained at ACE
hardware or Home Depot:
2 4" (75mm) M10 1.50 Stainless bolts
4 m10 1.50 nuts
2 3/8"ID x 3/4"OD x 3/4"long steel bushings Hillman #883499
2 BMX bike rear stunt pegs (Walmart has good ones for $10)
Cost about $20 + pegs
|Do one side
at a time.
Some BMX pegs are recessed like the ones I used
seen at left (I had them
on hand). Some are not. It may be necessary to drill out the peg
mounting holes to 3/8" (9.5MM) to accommodate the bolts. You will use
the double nuts as spacers like I did or on the inside of a flush
to get the spacing right. Your goal is to get the protrusion out of the
end of the frame cap to be 1" (25mm). Assemble your bolt and peg so that
the bolt protrudes 54mm or 2" beyond the end of your peg. Insert your
3/4" (19mm) Hillman spacer into the frame cap so that your bolt
protrudes about 1" when mounted. Be careful when you screw that bolt
into the actual frame. You will need to move the frame member some to
line it up. Cross thread is probable unless you are very careful here.
If you do cross thread, all is not lost. You can "repair" the threads by
rounding and slotting the bolt (click pic). Tighten to about 25 foot pounds. Ryde!
CAUTION! RIDING WITH YOUR RIGHT FOOT RESTED ON THE THIRD PEG WILL INCREASE YOUR BRAKING REACTION TIME CONSIDERABLY. WE SUGGEST MOVING YOUR RIGHT FOOT FROM THE THIRD PEG TO THE BRAKE PEDAL WHILE AT A STOP MANY MANY MANY TIMES SO YOU HAVE "MUSCLE MEMORY" OF THE MOTION NEEDED TO BRAKE EFFECTIVELY!
NOTE:I had a newer model F3 which meant I had "extra" channel stiffener sleeves/bolts shown above. The steps (in red) below may not be necessary if you have an older model with no pins.
The instructions for the F3-T that came with my bar, though much better than most others, got a C+ grade. Why? Totally missing were: (a) remove the rain guard completely - four T25 and a Phillips body clip; (b) remove a SECOND 10mm bolt and nut with a sleeve each side in the frame as well as the one that holds the block ; (c) remove the T27 from the under frunk shield and move it out of the way with a bungee. The installation was, with those exceptions, well described. Because you need to remove both the 10mm bolts, the frame member will likely slip and need re-aligned with the frame channel (scratch-all does work but you have to yank a bit on the orange arms so make sure you are sturdy with your jack). You WILL NOT get that bar out or in on a jack with less than a 24" lift with those SECOND bolts & sleeves in place.
If you just got your first set of tools for Mothers/Fathers day, get this done by someone else. I did most of the disassembly with the F3 on a steady ATV jack but found it necessary to let her down and raise the front with a full sized floor jack under the front frame to get clearance to R & R the bar. Adding a rubber 1-2 inch block to the jack cup would have helped a little as my jack topped out at just barely enough. The new blocks were a bit tough to get in so, again, make sure you are sturdy with your lifting equipment. I used a rubber hammer and a hunk of wood to tap them into the channel.
It was a bit of a sweaty chore to get it installed because of the extra steps which were not in the dox I had before I started. I read the instructions and decided to do it myself because I'm kinda good with a wrench. However, had those steps been included (which they are included now), I might have had a helper or got it done at the dealer (I hate doing that). At the finish, it was a toss up that I made the right choice (not as young as I used to be). Pics show the extra steps left out of the old but included in the new instructions that come with the bar. They get an A- from me now.
Now the meat:
Wheel bounce is greatly diminished. Wind resistance is at least doubled.
Cornering is so much improved that I no longer need to do the monkey trick quite so much to ride the twisties. (see this post >CLICK ME<)
The start up from a traffic light turn (say turn left once the light changes) is miraculous! Shazam! Just GO!
Drifting is greatly diminished on uneven, bumpy Ohio roads.
Yaw on crowned roads is greatly reduced and wandering is nearly gone (I haven't aligned her yet).
Feels like it's on rails. Shyza!

USING 2.5" BLUE HALO LED PROJECTOR LIGHTS
Get these LED fogs here from amazon or here from eBay. If you cannot buy at the link, make sure you buy solid white halo lenses, not the mosaic clear. These lights are great for conspicuity meaning they help others see YOU! For the fender, The supplied bracket is curled around the base of the fog lamp then zip tied to stay bent. The supplied Phillips screws with a washer added is used to mount light to the bracket top & bottom use Loctite or hot glue on threads. The assembly is then mounted to the fender using an M6 hex head bolt (not Allen - you need to get an open end wrench in there to tighten) plus washer into the top slot of the bracket into the original fender bolt threaded hole. Switched using an Olinco U19C2 push button switch with a blue halo (just like the lights) + the connector mounted in the OEM heated grips switch hole near the gas cap. The light's blue halo is connected to the GPS circuit so that they come on immediately with the key and turn of after a delay when the key is turned off. The wiring is 22AWG 4 conductor wire from Lowes with red & white twisted together as shown.

Get these LED fogs here. If you cannot buy at the link, make sure you buy ones that match the solid white halo lenses seen below, not the mosaic clear. These lights are great for conspicuity meaning they help others see YOU! The pattern at the left is for the two plates you must make for mounting. They can be any suitable material. I used 1/8" aluminum procured at a scrap yard for about $3. Choose something that is heavy enough to support the lights and is easy to work with. Paint them flat black (duplicolor truck bed liner?). The assemblies are then mounted to the body using 6 30mm M8 hex head bolts, 6 M8 and Nylock nuts and 6 3/8" fender washers through the holes in the frame behind the upper body side panels. Switched using an Olinco U19C2 push button switch with a blue halo (just like the fender lights) & the connector mounted in the OEM switch hole near the gas cap for the fog lights. The light's blue halo is connected to the GPS circuit so that they come on immediately with the key and turn of after a delay when the key is turned off. The wiring is 22AWG 4 conductor wire from Lowes with red & white twisted together as shown. You can run the power from the original OEM harness with the proper 3 wire connectors. If done with your own wiring like the lowers above, utilize the "USER" circuit with those wires. Remove the heat shields on the upper side panels to make room for the lights. To really polish the job get a set of LIGHT shrouds. Click here to see details in this picture and at the link.
This ol' trailer, a Pace 7' x 12', modified to fit my wyder Spyder
It was necessary to mod my old Pace 7 x 12 trailer which hauled my GL1800 wings for many years. One mod that I had already made to get my wings up into it on rainy days was to use roofing shingles laid down with truss/lath screws for traction on the slippery when wet wooden ramp. These now serve the drive wheel of the F3 admirably. The old doorway was too narrow to fit the F3 front wheels & fenders.
The next mod then was to remove the 3/4" door jam up to 24" from the bottom with a cut off wheel. I then laid down some paneling batten as a guide that was visible on the floor from the saddle of my F3 to keep the wheels aligned inside and spaced so that they would be centered preventing a scrape of the tires/fenders on the sides.
I have several loops on the floor through which to run belts to tie the old girl down. These combined with the F3 parking brake keep her settled & behaved until we get to our destination.
I have modified my center hi running lights so they work like a high mounted brake light by wiring the LEDs with a resistor and diodes as shown >CLICK<.
I have employed a new method to tie her down using an E-track strip and a single 2" heavy ratchet strap. However, what seems easy is knot! For the F3-T, getting a single strap over the rear tire for anchoring with E-track is a challenge. There are two methods. Remove the mud guard (which is a chore in itself***) and reach over the top of the tire to drop the 2" E-track strap down in front of it. Works great just like what the RT guys can do. Then re-install the mudguard once you untie her at your destination (another REAL chore in itself but see *** below).
With the mudguard on, it is impossible to get that strap over the tire and keep it centered. At your camping/trailer/hardware store, find the 32" heavy duty "pipe cleaner" Gear Tie shown. Fold it in half then thread it through the wheel spokes inside the belt pulley and bend the ends together in a hook pattern. Loop the 2" E-track strap over it & push it up as far as you can reach on each side of the fender, then roll the bike forward about 28 inches. Reach between the muffler and the rear side cover and flip the strap toward the front where you can grab it with a telescoping magnet and pull it through. Hook it into your E-track and move the bike back to where you need it for weight distribution. Unset that brass then re-set it just in front of the tire. Using another belt's brass, thread the working strap through the slot and then clip that brass just behind the tire. One cannot use an E-track idler because it's too high so we make an idler out of the second strap (which will work well with a plain F3 rear fender). Go through the ratchet as normal and crank it tight. To make a bit more firm, let some air out of the tire and crank it tight then put the air back. We also gain another strap for use on another setup. Harbor Freight has all the E-track parts you need and any camping store has the 32' Gear Ties. In addition to the single strap, I have replaced the lower front shock bolts with M10 x 55 stainless eye bolts for tow or tie. They will accept soft ties or hooks for tow to pull up on a flatbed or for tie downs if need be. I got them on eBay for cheep then cut them to size with a cut off wheel and used the OEM M10 nuts for a solid mount.
*** Having been completely frustrated (another BuRP engineer fuvx up) by trying to re-install the mudguard to its berth, and because in so trying I broke off two of the pins, I re-engineered the set up using some brains and real world experience (unlike the BuRP guys which have neither). I used some dykes and cut off all the pins. I
fitted the two body pins in the bags with new black #8 screws from AutoZone. I then duct taped the mudguard to the fender in place leaving space where my screws were to go. As best I could for alignment, I drilled four holes through both the fender and the mudguard with a 1/8" bit while holding the mudguard firmly in place. With a firm grip on the guard & using a low speed low torque power driver I ran 4 #8 of the AutoZone #45570 screws as shown in the pic. This snugged the assembly nicely. Now to pull it for putting the single belt on, I just remove the 6 screws and once you yank the body pins from the bags, down goes Frazier! Easy peasy. I now can easily remove the mudguard for tie down just like the RT guys can do or to show off my Kumho tire at bike night (making sure I don't encounter wet pavement*). And putting it back is painless for riding. This has a bonus for removing the rear wheel for tire mounting as well. Eventually the screws may loosen up so I can switch to #10's or afix the 054030 Jnuts to the mudguard.
*And if you ask "Why don't you just leave the mudguard off?" Here are two pics of a ride I took with it off and merely encountered a single 3" stream of dirty water coming off a driveway. All the speckles (pic1 Pic2) are from just that single 3" stream. I had some on my jacket back and some on my helmet. Imagine if I had encountered dirty construction water for miles! No thanks. And a side note, there is a gasket in the fender and and drain holes in the mudguard.
Desperately hating Torx. I am on a mission to eliminate all Torx (star) screws on my F3. I am using m5 x .8 x 20mm stainless black oxide pan head phillips screws. I got them on Amazon but you might be able to find them elsewhere. I bought 50 of them for $13 on Amazon. Considering that each of the OEM Torx are $4 each and just one side needs four it's a bargain. I also use these on my quad as well.
|Bought a 36mm combination wrench for belt adjustments and tensioning from Menard's. I cut it in half with an angle grinder and cut off wheel to use it on both the axle bolt (box end) and the axel nut (open end) without pullng the split pin. Axle nut torque is 160lbs. Got a $9 36mm socket off Amazon for both the axle and oil filter cap which makes getting the oil cap off a breeze! Used a Krikit 2 for checking the belt tension which should be between 160 and 190 by that gauge with the wheel OFF the ground following instructions in this video.|
Bungee loops for tie downs & RACK
The problem with tie downs across the back seat... Bungees mar the handles and or the seat vinyl. What to do? You could buy some expensive bungee hooks or such, but I have fixed it for pennies with black paracord. You can choose another color, but all you need to is tie a loop of paracord using the bowline knot as shown at right and capture it behind the big washers. Make sure you melt the paracord to itself at the knot to avoid inadvertent undoing.
I run a $70 Quansheng TG-UV2 and/or a $25 Baofeng UV-5R both purchased a few years ago. I have two of each. The radio is hung on a homemade panel mounted to my right bar with extended screws and spacers as shown at right. I put a hook Velcro piece on the mount and each radio has under the belt clip on the battery the loop Velcro mate which prevents the radio from rattling and ensures it stays in place. I use just the Rubber Duck seen at left which works well enough for bike to bike communications when the radio is mounted vertically on its bracket.
The wiring diagram for keying the headset is shown at left (just mash the ground of the pins together).
I built my own key method for my special needs boom mic. I used two very thin terminals to insert under the radio's headset pins so they touch the GROUND on each pin. To those I soldered the red and black wires (keeping them isolated) of the cut off MALE end of a 1/8" headphone extension cord. I used silicone molding compound to make them stronger and keep them spaced. I found it necessary to grind down the shoulder of the headset hollow on the Baofeng radio to keep the terminals from breaking. For the key button, under the throttle I mounted a momentary switch which shorts the ground & red wires of the FEMALE end of the extension cord. For that I made another bracket by drilling two holes in the bottom of the right switch housing and put through a pair of #10 screws to mate with the holes in my homemade bracket. The material for that bracket was simply a length of aluminum carpet edging (pic) which is cast bent for strength. I mount the radio on its bracket and plug the male radio 1/8" into the bike's female 1/8". When I press the momentary it mashes together the pin grounds and keys the unit.
INJOY! And shout out for KD8OVH from time to time. I can be found in NE Ohio and North or South Carolina.
