I think what Steve is suggesting, and your recent troubleshooting reveals, is this:
The A/C WOT Relay is made to cut off the A/C clutch whenever you go WOT (to disable the A/C and free up some more horsepower when you obviously are demanding for it...) You already know that the WOT relay is the "t" shaped relay.
That relay is connected to your A/C clutch relay via one of the four prongs, and comes in to the bottom of the fuse holder on a violet wire. (the wires going to the "A/C clutch relay" fuse holder slot. When you insert your A/C clutch relay in to the four holes, the OTHER side of those holes have these wires connected to them: You should have a violet/blue(ac signal being passed, a violet black(A/C signal source)the violet I mentioned(AC WOT signal), and a ground.

You've either got a faulty WOT relay
OR
the relay is working fine, and you have stray voltage being passed to the WOT relay causing it to trigger (knicked hot wire touching the relay's casing, or signal input [soldered connector] etc, etc..)
OR
You have a faulty PCM output, telling the relay you ARE at WOT, when in fact you aren't.
Steve can come in here to give more followup shortly, I am sure.
