Hello Keith,
With your vehicle, if you want to manually engage the a/c clutch it is best to use a jumper wire, remove the a/c clutch relay from the PDC next to the battery and with the jumper wire connect terminals 30 and 87 of the A/C clutch relay connector. This will engage the Compressor.
Jumping the wires at the Pressure Sensor will NOT engage the clutch and if you short out the 5v supply wire, it WILL kill the engine. This kills the 5v output to all sensors for the PCM and causes the engine to stall.
Here is the wiring diagram for the a/c clutch so you can tell what I am referring to....
