Does anyone know what color wire the reverse light positive is. Also what color is the positive wire on the E Brake in a 2001 F150

You need to post this in the correct forum (vehicle specific wiring).

E-Brake is Lt. Green/Red, but is never positive. In all my days and all the cars I've worked on, I have never seen a positive E-Brake.

I have no info on the reverse wire though, sorry.

Depends on the year. My 03 it is on the drivers side low in the kick panel. Black wire, pink stripe. Some trucks have it on the passenger side, same color.

You could have tried to S E A R C H

It works nicely.
