Hi Andy,
OK, there is a small solenoid usually mounted between the wing and the fuel filter (usually bolted to the ABS block if you have it). The solenoid activates a vacuum that triggers a diaphram that pulls a rod on the side of the injection pump - as the rod moves it pulls on the part of the throttle linkage increasing the revs.
If you look at the injection pump from over the wing, the diaphram and rod is part of the assembly that is bolted to the side of the pump with the diaphram being down and near the back - it is a brass coloured 'ball' with a rod going out of it to the left and a rubber hose going out to the right.
Now, looking at the electrical wiring diagrams the circuit for the compressor clutch and the circuit for the idle up are linked and go back to an 'AC Cut' relay which is linked in to water temperatures - this relay appears to be up behind the glove compartment. The other thing to double check is the A/C ECU which is up above the pedals and also the fuses ECU-IG, ECU-B and A/C in the fuse panel to the right of the steering wheel.
