Well I got a bubba splice in my AC wiring and it's pretty confusing I was hoping that someone had a schematic for a 79 that included AC. It's off the green and light blue wires that plugs into the the bleeder valve on the hard lines and goes on to the compressor. There are 2, two socket plugs and a black wire with a terminal. The AC wasn't working or hooked up when I got the car but it would be nice to sort this out while I'm doing the engine bay wiring. Nothings hooked up either and I can take a picture if it helps!

The 2 connectors that you're unsure of go to the thermostatic/compressor control switch and to the compressor. The one with the black pigtail attached goes to the compressor with the black ground wire attaching with the same bolt that attaches the upper support brace to the compressor bracket.
The comp. control switch is a cube shaped thing(about 1 1/4") attached with a bracket to the front of the firewall kickout next to the accumulator(the tank shaped thing tucked down in the fender well). Kinda below the overflow tank.
