from the factory ford gray harness i have three wires for the head unit that i take as something along the lines of the illumination for the faceplate and one sony harness wire for the actual dimmer. Anyone know which one i should hook up
ford wires:
illumination
positive dimmer
negative dimmer
sony wire:
illumination +
and just for the record i would love for the head unit display to dim with the guage cluster lights
