Ok, popped the hood on my 79, and found that whosonfirst had started changing the engine harness from a 4 cyl, to a v6 harness.
I managed to remove all but 1 wire. It is a black wire with red stripe. I don't know what it's plugged into is for. Any ideas? Is this just for 4cyl engines? There is a 2nd box(relay?) mounted on the right inner fender. I'm guessing that one is for ac? Any help is GREATLY appreciated. Brad
