I would like to get some help from one of the 2004 owners that have personally removed the PCM unit. I see two black/gray modules that are mounted on the drivers side fender, just across from the brake resivore. After doing a search on the pcm unit, it sounds like the 03 & o4's are in a different location that the 05 & 06's. How can I tell wchich one the PCM is, and how do I remove it.
Thank's
