I basically need a diagram of how to wire two relays to (2) AIR RIDE compressors that is triggered by a pressure switch. Any help with this would be great.

What are you trying to get the relays to do? Trigger them by what? Alarm keypad?

Dude, follow the instructions that came with the system. Chances are you will wire a switched power to pin 86, ground trigger from pressure switch to pin 85, constant power to 30, and 87 will be ouput to compressor(1 only). You will need two relays wired the same way.

Note 1 would be fused 12V either direct from battery or from an underhood fuse block. This also shows an optional "manual on" switch for the compressors for those times you don't want to wait for the press. sw. to kick on or if the press. sw. should fail.
