I have never hotwired a compressor, so I don't know which wire does what.

OK, lets go through the list one more time:

The ECC does not blink the yellow lights at start up.
The fan is in the 'auto' position and blower is running.
The AC switch is green.
The temp dials are set to 64F.
The outside temperature is over 42F.
There are no compressor clicks while the ECC system checks itself at engine startup.
Shorting the pressostat wires does not engage the compressor clutch.
Pushing on the clutch plate doesn't do anything.

All that is left is to check the fuses and the AC relay. Even with a small amount of coolant pressure, 65lbs, it should be enough to get the system cycling. The warmer the outside temperature, the greater the pressure, with the same amount of R134a.
