Re: Tail light wiring question.
You only need three wires- brake lights use the same wire as the turn signals.
Whichever wire has voltage with just the headlights on will slit into two wires(one to each side) for tail lights. The remaining two wires should be a left brake/turn and right brake/turn. There is no seperate wire for brakes lights IF wired correctly.
On your new lights- the orange wire is the brake/turn signal, the black is the tail lights.
The lights are suppsoed to be self grounding thru the mounting studs.
If you look farther up the frame, you should find the original wires, there wil be a brown, yellow and green, unless someone has re wired the whole harness from front to back.
