I finally got the interior a/c installed after some previous owner removed all the interior stuff. The blue and red wires for the unit obviously must plug in to the fuse panel, but the plugs aren't compatible. The unit is from a 78 and mine is a 79, could that be why? If not, is there a fuse that's supposed to go in between the panel and the unit that I'm missing? Does anyone have a picture of the fuse panel with the a/c stuff plugged in? I can't find on on google.
Also, does the turning on of the blower initiate the turning on of the compressor? If so, mine doesn't seem to be working. Is the wire on the compressor a ground that's supposed to magnetically pull in the clutch?
Compressor clutch wire gets 12v to energize the clutch. The case itself is the ground.

The AC compressor power is marked 50 Brown 16 (16 ga wire)
I have not found the control wiring for the under dash AC unit. It must be buried somewhere else. The heat/defrost controls are different from the AC controls. They are totally separate systems. That said, you can run heat to defrost the windshiel and run the AC at the same time.
Yeah I couldn't find anything in there. I guess I'm wondering if the fuse panel plugs on a 78 are different than 79, and should I just make something work. I don't want to cut it if I don't have to.
