The PCM is easy to access. It is behind the passenger side kick panel. Remove the passenger side sill plate on 2dr models or partially remove it on 4dr models. Remove the trim screw from midway up the kick panel in the door gap area. Then reach behind the kick panel on the firewall end and pull it out. The round Christmas tree style trim fastener and panel will come out. Now you'll see the PCM. It is held to the body by a white plastic strap. Remove a screw or two allowing you to pull the strap off the PCM and slide the PCM out, with wire loom attached. You can now read the catch code on the PCM (example UMP1) to determine which model PCM calibration you have. Loosening the bolt on the wire harness connector will allow it to be disconnected from the PCM.
