Yeah, It's hooked up correctly. It would start, rev once, then
stall. Yes, I'm sure I have the SKIM key, as last year we lost it for
a few days and were going to have to fork out $300 to the dealer to
have it replaced.

I put the old PCM back in, and I'll take the new one to the dealer
tomorrow to see if I can get it reprogrammed wihtout being raped by
them. On second thought, I might go to the Jeep dealer in the rough
part of town. The one closest to me is in a ritzy area and they seem
to specialize in the old rip off.

I really hate the fact that I can't do this myself.

Thanks for the replys.
