Hello again, I have another problem that should be easy to resolve but it is driving me crazy. The rear lights have 3 wires, one white ,one black and one red. the way I see it one should be for brake light, one for turn signal and one for the lights. I need to find the one that only has power when u turn the lights on. 2 of the wires have constant power and the other doesn't seem to have any. I cant get it to light up. I have tried to splice into all the wires one at a time and cant get anything to work. I don't know where to go next.
