My new serpentine pulley/clutch came in the mail today. So how do I wire up the compressor clutch?

From the Clutch to a pressure switch, the other side of the pressure switch to a 12 volt ignition wire!

RE: pass, pass, pass,pass... fail!!

I don't know if you have the same pressure switch as I do (the square D from onboardair.com) but if it is the same, you'll have L1, L2, R1, R2. Your power will go into either L1 or L2 and come out to the clutch from either R1, or R2. Or vis-versa (however you spell that word). I have pictures of my setup on my cardomain site which is in the link above my picture.

Oh ya. Make sure your power to the pressure switch is hooked to a switched power wire from the ignition, not constant (battery) or your clutch will stay enguaged if the jeep is shut off with pressure below what the pressure switch is set to.
