The problem I am having at this point is terminology and what component is actually where.

The only thing I think I am 100% sure about is the wire coming from C2-43 on the computer that goes to the A/C compressor clutch relay in the fuse box that then goes to the plug at the compressor.

The light green wire from the HVAC control module is supposed to go to one side of the Low Pressure Cut-Out Switch, but now I'm not even sure where that is.

C2-11 A/C Cycling Switch
C2-17 A/C Request Signal
C2-33 A/C Recirculation
C2-43 A/C Compressor Clutch Relay Control
C2-55 A/C Low Pressure Cut-Out Switch

I thought for sure someone in the San Diego area would be able to help me out, but none of them want to deal with wiring.
