OK here's the deal, I've been using a mototech undertail for about a year. I bought it when they on there way out (which I didn't know). Unfortunately, the lights quit working, all of them, brake, running and turn signals. I bought an ebay undertail a couple of years ago just in case the one on the bike took a dump.
This is what the undertail directions say "Proceed to do the wiring for the lights (remember all 4 sets of wires must be connected).
Black is ground
Red is brakes
White is running lights
Green is turn signals
Note: You will have 2 wires coming from your turn signals, power and ground. You Only need to connect the power cable and not the ground cable.
However, heres the real deal; the plug that goes to my rear lights has wires for the tail lights, brake lights and a brown wire that comes from the ignition switch. I connected the turn signals, and in contrast to what the directions say, you have to connect the turn signal ground. The turn signals work.
I hooked up the brake lights and the tail lights and they don't work. Probably because I don't know where to hook up the brown wire coming from the ignition. I tried hooking to the tail lights didn't work. I tried hooking to the brake light and blew a fuse. Turns out according to the wiring diagram, that the brake light wire goes to ground.
So at this point, I am pretty much clueless as to where to connect my power/ ignition wire. I hoping you all have some ideas. This can't be this hard..
