Anybody have a diagram of all o the wires going into the Ecm inside the drivers side fender? I'm having trouble finding it in the book

Should at the back of the electrical section. My 93 manual has it on page 8W-124 and 8W-125.

Nope. That page is fuel gage and seat belt warnings lol

Found it page 8w-132 in my 1992 manual. Only problem is there's more wires than the diagrams showing

Been thinking about this statement and I finally had a thought as to maybe why. Is your truck a true 92 or a late model 91.5 that was registered as a 92? On your motor do you have a CPS? If not then you actually have a 91.5, not a 92. And this could be why the 92 FSM shows more wires then what you have...since the 91.5's had a few functions that were not controlled by the ECM yet.

Here is the PCM pinout for a 91, hope it can be read.
