Re: AC Compressor Question
I have no direct knowledge about anything to do with a JK but a good tester can help determine which wire is normally used as a ground, or a 9V battery when hooked to those two wires for an instant will help you by engaging the clutches on the compressor.
Re: AC Compressor Question
I think technically its a LJ (Unlimited wrangler). I'll see if I can round up a test or buy a cheap one from HF. Or even try the 9V trick, though that would be more out of curiosity than anything. :D
