Technically A PCM is in a vehicle where the computer does all the shifting of the transmission.
Your truck has an ECM in the area behind the glove box.
If I can find some free time tomorrow, I will see if I have a schematic for a model year earlier then 1993.

Did you give the model, year, engine, fuel system type, and transmission information?
If it is modified from what came stock from the factory, let us know that too.
