I am in the process of hooking up the a/c in my 72 cutlass 442. The wiring harness on the ac is the only one I have not replaced so far. I am not sure what this wiring connector connects to. I know/think that the 2 prong connector to the compressor comes from this connector and I am going to have to fix it but I have looked and cant find anything this connector goes to. Its a 3 prong connector. Anyone have a picture that shows what it connects to or can tell me what it connects to. the other wires are in tack, here are the pictures I have taken

 

Thats the plug where the thermal limiter fuse plugs into. It clips to the compressor bracket. There should be a compressor connector that connects to the empty slot on that one with a green wire.

Picture:

 

thanks Rob, is the thermal limit fuse what I am seeing plugged into that 3 way connector on the compressor? If so I am going to have to find one of those as well

 

Yes.
These fuses came from advance autoparts down in South Carolina. I was amazed that they had them in stock! Hope you can find them locally. OPG has them in last resorts.
