Okay I just checked my truck, it is the same as yours. I have 3 12vs the brwn, blue/orange, and blue/black the blue is the trigger (I believe since it has 12vs once you apply power to the volt meter) what's weird is I have all mine bypassed lol......
If you wire it to how Jim Lane has it your pressure switch will still cut out...I just unhooked switch to make sure it cut the compressor out and it did....The Only problem I had was it would keep the compressor locked until I ran it to ignition power for to control the relay.
