I have two ACC switched on my dash. My dash is the old style with two rows of switches right of the steering wheel and then all the fuses on the left of the steering wheel. Two rows of switches. Trying to figure out what the top ACC switch goes to. Tried tracing the wires to no avail. If anyone has a wiring diagram or knows that that switch is for, I would appreciate it.
