Has anyone hooked up there A/C wiring yet to there LS1 swaps? Not the 3rd gen ac the 4th gen AC. what wires did you hook up? I notice that the 3rd gen has 2 connectors and that the 4th gen AC has 1 connector??? Help PLZ

 

I havn't hooked mine up yet. However with my corvette wiring harness, there is 3 large connectors that went to the LS1 underhood fuse block. the first one was the engine wiring harness, the 2nd goes into the passenger compartment of the car, and the third was the wiring for the lights, horn, and other things up front in the engine bay area.

It was this 3rd connector that had the A/C compressor plug on it. We went through and removed all the wires from this connector and kept the ones we wanted, the only wires that we kept, were the connector for the A/c compressor and the wires that powered the cooling fans. I believe the AIR system was also connected to this block.

My guess is the f-body and vette fuse block is set up similiar to each other, but i don't know this for sure. The corvette A/c compressor and f-body compressor apear to use the exact same connectors on their compressors.

Hope this information helps some.

Thanks for the info bro, but by any chance would you know what wire i should use out of my old harness to the new A/C compressor?? This a really tricky thing to figure out. thanks

I personally don't know, i havn't gotten this far yet.

My guess is your gonna use one wire that comes from the A/C compressor relay(which the relay should be part of the 3rd gen harness) and then a 2nd wire that will need to grounded.

Anyone know for sure the correct way to wire it?
