well i have another post to do with cold start issues and after fiddling around with the plug connection on, what i believe to be, the PCM i just wondered how hard it is to get out and what to clean the connections with. also i can see what i think is the PCM but there is also another metal box, little smaller, behind it, kinda piggyback to it, there is also a white plastic box mounted to its side on the drivers side. the bigger box has a white push on plug with a bunch of small multi colored wires and the smaller one piggyback to it has larger plugs with black shielded wires. all i know now is that i went out after my truck sitting for over 6 hours and started like a new truck.
