Autometer FP guage
I have my red hooked to a keyed 12v. source and obviously the black wire grounded. Just need to no where I can hook the white wire which I guess is for lighting. If it helps gauges are mounted in the center a/c vent.

Electric. Instructions say hook white to a lighting wire for dimming with the factory gauges. Just need to know is there such a wire in the radio area and what color would it be?
