  I believe that one has two green wires. It's a big knob of a thing 
and simply interrupts one of the wires going to the compressor in 
the event that the engine get's too warm.  
  GM's have a high temp/fuse on the high side near the compressor.  
There's a thermal plug in the reciever/drier and high and low preessure 
switches in the lines.  High side COULD be thermal instead of 
pressure so I mention it in case.  Depends on where it is in the 
wiring and the color of the wires.
