My Jeep is unavailable for a picture right now, but it's easy to find.
It's located in the engine compartment on the passenger side of the firewall, aft of the coolant reservoir. You will have to remove the reservoir. The PCM is a square metal box mounted vertically to the firewall with three bolts. On the front, you will find three large rectangular connectors, one black, one white, one gray. Beneath the two outer connectors, you will find the two screws. You do not need to remove the connectors. The screws use a #25 Torx bit for removal. Back the screws out about 1/4" and see if that makes a difference. If you have the same problem I did, install two new 1/4 or 3/8 #6 sheet metal screws and your good to go. If not, come back with detailed info and I'll try to help. Good luck, and let me know what happens.
