There is the clutch and high pressure switch on the compressor itself. Clutch on the front and switch between the compressor and engine. You also have your coolant temp sensor on the thermostat housing. Also a connector on the fan towards the bottom pass side of the fan unit.
Looking at the wiring diagram again...is it possible you have an R/T harness? The R/T has another connector coming off the same harness in the same vicinity as the A/C clutch connector. It's for the manifold tuning valve solenoid which was exclusively on the R/T package. There are 2 wires... BR/YL....BK. Hope this helps.
BTW....I'm just throwing out ideas....not a expert by any means but I've been working with another guy on here sorting out a mess of unplugged wires from a horrible swap.
