Started putting the fresh center console parts in my wife's '84 (thanks, handymanpat!) and noticed something that made me concerned. There's a wire in one of the harnesses that has burned way back into the harness. I can't find anything in my Chilton's identifying radio wires (or the heat/ac wires), showing how far back I may have to chase this. To help eliminate what it ISN'T, it isn't in the heat/ac or fan speed switch harnesses, and it's not in the 4-wire 16 gauge (light blue, dark blue, brown, yellow) bundle (need to know what these do; rear/headrest speakers, maybe?). The wire in question is in the 7-wire 16 gauge bundle (light green, dark green, tan, grey, black, yellow and the burned one with a light-colored jacket). This car came to us with a poorly installed aftermarket stereo, and it has been troublesome at best. Can anybody help me identify the purpose of this wire and where it goes once it hits the main harness? Thanks in advance - Chris

May have just stumbled on the answer... two grey wires in that particular bundle. One is a front speaker negative, the other comes out of either the headlight switch or the dimmer wheel. My bet is it's the illumination wire that shorted to ground...

BTW, still curious if anybody knows or remembers whether that wire goes to the headlight switch or the dimmer...

I am pretty sure it is from the headlight switch. It tells the radio to go in to "dim" mode when you have the lights on.

Can you post pictures?
