Just for illustrative purposes I decided to post up the wiring of the ACC brown wire that the fellows are talking about. I think they have it nailed down and you'll be able to see that in the diagrams.The first one shows the ignition switch wiring and the 12 gauge brown ACC wire on the switch.
This one shows the ACC wire going to the fuse panel and feeding the Heater,wiper,and turn signal fuses. It is indicated by the black arrows.
The brown wire near it is the heater switch feed wire, the yellow wire is the windshield wiper motor wire, and the purple wire is for the turn signals. It runs from the fuse panel to the steering column connector and up to the turn signal switch.
