Six wires run to the stock tail light assembly: red/yellow, orange/white, black, violet, blue, brown. I know black is HD ground, can someone give me the run down on the other five wires. I know they will be running, brake, right turn, left turn, and ?. Thanks for any help on this.

 

red/yellow and orange/white, and beige? (one wire is abr. as "BE")are to the tail light

violet is left turn sig. and brown is the right.

 

The red/yellow and orange/white are brake lights, you only need one of them, at least on my 05 WG I only needed 1.
Wiring schmatic shows one for front the other for rear, but both work on the red/yellow on mine. I capped the orange/white.
Blue is tailight. As mentioned above, violet and brown are turn.

 

Could've traced them out I suppose. But rebuilding after an accident and hobbling around the bike on crutches, I need a few less steps. Thanks again!

 

Glad to be of some help.
