With the pin jumped from the cabin switch to the compressor the clutch engages and blows cold. That's without the pressure switch bypassed. If I pull the wire on the pressure switch it all shuts off, fan and compressor clutch. This car only has 5 pins, 1=12V Dash, 2=Ground, 3=12V Battery, 4=compressor, 5=fan relay. So the only thing I'm really bypassing is the fan relay (ground, 12V+, and #5 fan), but the fan works independently of the AC relay.
Considering nobody in the area handles R12 and worst case the freeon escapes enough to cut out the pressue switch, I'll wait for that to happen before I do anything. So far it works great and will definately freeze me out of the car on full blast, even at idle.
