I am installing some LED lights on the interior. I have it all set and wires fed through their respective spots. I am trying to crimp it with the headlamps, so that when I turn on the lamps, the interior lights turn on as well. However, the Haynes manual I purchased said that the head lamps on wire was red/white. I clipped and crimped and did it all, and nothing. I tested it after the failed attempt and left the wire separate and the lamps still came on? Does anyone know which wire that goes into the switch actually turns on the head lamps? Thanks! Nate.
