Default What to do with A/C wiring for swap?

I'm following the harness info on lt1swap for my swap. I have a 98 chevy c1500 and am putting a 04 lq4 in it. I have a harness from a 01 silverado, drive by cable. I'm working on the harness and got most stuff figured out except for the a/c wires since lt1swap takes them out. here is what i got, 3 connectors


1. Black-Ground
Dk Green-A/C low pressure signal switch

2. Black-Ground
Dk Green- A/C compressor clutch solenoid feed

3. Lt Blue- A/C high pressure cutout switch
Dk Green/white- A/C Request signal

Can someone help me out here i'm not sure where they go. I'm planning if possible to use my stock a/c system with a different compressor. Probably a compressor out of the 01 silverado if it will fit. Just not sure where the wires go.

Pocket, did you ever confirm that the "truck schematic" you posted will work? That is exactly what I did with the harness I'm sorting out right now, but after a second thought on it, I need to know if the computer will provide the ground for the compressor when it sees the +12 at the signal wire, regardless of the low pressure switch input at C2 pin 55.

I wish I would have known about the wideband control using EGR wires before I yanked all those pins.
