Ok guys here's the deal. I'm installing a factory ac box into my 80 camino. It is complete except for one bit. At the end of the wire harness under the hood it's been cut off. There's a light green wire, a dark green wire and a thicker red wire. I believe the two green wires had a connector that would have connected to the factory r4 compressor. Question is where would the red wire connected. Also I'm putting in a sanden 508 1 wire compressor. How do I connect that? There also isn't a connector for the cycle switch on the accumulator. Any help would be appreciated.

Not sure about 3 wires. My car has 4. Black and dark green that go to the compressor. Light green goes to the high idle solenoid and red comes from the bulkhead connection. Maybe someone else has better info ?
That red wire (12 GA circuit 2) is the main power for the blower relay. On the engine harness it's spliced into the one main red wire the has a fusible link at the starter & goes to the alternator & C100 firewall connector. The light green (18 GA circuit 66) feeds off the pressure cycling switch & goes into the dash control panel. Engine side it goes to the fast idle solenoid on the left front of the carb. The dark green (18 GA circuit 59) comes off the pressure cycling switch. On the engine side it'll go right to the compressor. As for the missing I'd suggest to get a '80 service manual to ensure everything need can be gathered up as not all years are the same. There should be a few members chiming in that have used Sanden compressors.
Also to add to this catastrophe, I have taken out the v6 and am putting in a 355. I don't have a fast idle solenoid. The pressure cycling switch is 2 wire. And I'll post pics of the main and ac wiring harness. Most of it I know where it goes some of it I don't. The first 4 are of my main wiring harness and the last is the ac wiring harness

going from a v6 to a v8 doesn't have any effect on the wiring portion so don't let that weigh you down
also not every car has/needs a fast idle solenoid so don't sweat that small detail.

Just wanting it to work. I don't know what I need to have and what can be deleted. Just ordered a Haynes and a Chilton manual.
I beleive OP is attempting to replace the factory installed heater only in his el camino with an A/C box pulled from another gbody car... i wonder if it would have been less hasle going with vintage air instead, if available that is.
I also have a 355 SBC in my Regal and I made a mount for a solenoid to fit my throttle bracket for the Holley carb and of coarse I polished it too.
I'm rebuilding it this weekend with new seal and cores to replace the non ac box
