OK, here are just some notes and photos to help anyone out there who gets a L&M Fender with the Run/Turn/Brake light module. These tips can also be helpful if you get any other lights - LED, filament, whatever - so you know which wires to cut.
Firstly, the Run/Turn/Brake light that I got with my L&M fender is the red run/brake and the amber turn signals. There are four wires clearly mentioned in the instructions:
This is a pair of wires that leads to a single wire (sort of a Y connector):
However you are most comfortable splitting the original wiring harness to possibly reduce the amount of wire you need to tuck away - that's your call. But, when all is said and you're sitting with cut wires, here's how you tie them together:
Later in this thread did I come to realize and mention that I needed to do a better job of connecting these wires. I found a trailer light extension kit (32" long) that made me realize this was the best solution. What better weather-tight connector should reside under my fender (rhetorical question).
So, here's that harness:
Trailer Lights 32" Extender
One issue was that I was trying to create a 4-pin to 4-pin connector mating system. This extension, I realized after I got it home, did NOT have the ground pin on one end of this extension. In the end, that was ok. I just tied all the ground wires in the original harness to the frame. I then butchered this harness' ground wire to get that screw-loop and attached it to the ground lead on the Radiantz light (black) wire.
So, I cut the harness in half and use one end to attach to the factory harness and I used the other half to attach it to the Radiantz run/brake & turn wires.
Taking the above wiring information I stated, here it is updated for the trailer harness wires (THW) incorporated:
This section of the how-to is how I ran the wires.
First, using the guide above, I connected all the wires accordingly - including my Kisan Tech SM-3 (wiring map below) - after cutting a lot of excess wire out of the original harness.
Next, I used a 32" long trailer light connector to make a better quick-disconnect for this whole wiring fiasco.
Here is the underside of the fender where I placed a yellow mark for which to aim to run the wires from the Radiantz light. I did NOT want to run dead center and pinch the wire where the rear seat/pinnion screw meets flush with the fender. You see - the fender sits atop the three screw mounts for the seat & pinnion, so there's a slight gap between the frame and the fender for the wires to be run w/o rubbing. Anyway, that photo:
Here is a pic of the preliminary tape-down of the wire right on target:
Here I did a dry-fit of the fender to make sure my wires were long enough to mate-up:
This is the final tape-down using Aluminum Refrigeration Tape (very sticky):
Use a credit card or semi-hard plastic edge to run across the tape where it meets the fender to ensure the glue beads on the tape are activated for proper and extreme adhesion.
After installing the fender, I was able to connect the trailer connector to complete three of the connections ...
... the fourth connection was Ground - and I tied that directly to the frame with its own dedicated wire (because the fourth connection in this trailer extension kit was not included):
Kisan Tech SM-3 Turn Signal Cancellation Module:
If you have the Kisan Tech turn cancellation module for your bike, the wires you need to splice with the provided splicers are as follows:
As usual, post questions and I or someone else in the know will answer.
Firstly, the Run/Turn/Brake light that I got with my L&M fender is the red run/brake and the amber turn signals. There are four wires clearly mentioned in the instructions:
Red - Brake
Blue - Left Turn
Black - Ground
Yellow - Right Turn
Next, when you disconnect the connectors so as to remove the entire rear light assembly, you will have three plugs left unattached:Blue - Left Turn
Black - Ground
Yellow - Right Turn
Orange 2-pin Plug - Orange Wire (hot), Dark Green Wire w/ Silver spots (Ground) - Left Turn
Light Blue 2-pin Plug - Blue Wire (hot), Dark Green Wire w/ Silver spots (Ground) - Right Turn
Light Blue 2-pin Plug - Blue Wire (hot), Dark Green Wire w/ Silver spots (Ground) - Right Turn
Opaque 3-pin Plug - Green Wire w/ Yellow stripe (brake), Brown w/ Silver spots (Run), Dark Green w/ Silver spots (Ground)
Lastly, when you have the Run/Brake light combo in one LED, you will also receive a wire set called a Dual Element.
This is a pair of wires that leads to a single wire (sort of a Y connector):
Red Adjacent ----------\
........................\
.........................>-------------- Red Solo
......................../
Orange Adjacent -------/
Update: I thought the following was correct about the dual-element setup:
........................\
.........................>-------------- Red Solo
......................../
Orange Adjacent -------/
I have since tested the line for the voltage with ignition on and then with brakes applied and I'm not seeing a voltage increase, at all. However, I am seeing a current jump from running - 32mA (0.032A) - to braking 54mA (0.054A).Embedded in the shrink tubing where they're joined is probably a diode to ensure when the brake is used, the +12V coming from the brake line doesn't back feed the constant +12V running light line. There is also a resistor to cut the voltage to something lower than +12V for just the running lights (Thanks for that clarification Clueless). When the running lights are on, the Run/Brake LED module probably gets +6V and produces a nice and bright running light. When the brake is applied, an additional +6V feeds into that Y-type connection creating +12V to the LED to - obviously - increase the lights' intensity for braking. Anyway, I digress.
However you are most comfortable splitting the original wiring harness to possibly reduce the amount of wire you need to tuck away - that's your call. But, when all is said and you're sitting with cut wires, here's how you tie them together:

Harness Green w/ Yellow stripe Wire -------> Dual Element Red Adjacent Wire

I really hope this helps someone - especially those who are typically intimidated by electrical mods. This really isn't that difficult. The hardest part was finding a way to store all the wire from the harness AND the fender.Harness Light Blue Wire ----------------> Kisan White Wire
