I found a wiring diagram for a 79, is the 1980 the same or does someone know where I can find one? There is a connecter coming off my brakelight switch and I dont know what it controls. It has three wires coming from it, (2) brown and (1) pink with a black line. Having this connected or not seems to make a big difference with the amp gauge.

Here is a colorized partial diagram for the 1980. Note the configuration for the cruise control switch.
Thank you so much for this diagram! This answered all my questions... the two brown wires and the pink with black line are for the cruise control that has been disconnected and im guessing shorted out somewhere. Do you have a link for that diagram that I can download?

That colorized drawing does not exist anywhere else. I colorized it myself and I don't remember where I got the original b&w one.
