99 Tahoe Fuel pump Wires/PCM Diagram
Hey Yall, PO transplanted driveline out of a 1999 Tahoe into 66' C10, and well lets just say wiring is sub par lol. So i need some help finding a wiring diagram of the PCM, and if anyone happens to know the colors of the fuel pump wires? Or has a diagram for that? Thanks in advance!

Re: 99 Tahoe Fuel pump Wires/PCM Diagram
Did you ever get the service number from your PCM that I asked you about in your other thread? You will need that number so that you have some sort of idea of what you are working with. Here is a link to a page to get you started, but that info may not be correct depending on what PCM you have.

Hey Captain, got swamped with work and all but finally got a pic of the bottom of the PCM, and added it. Hopefully it helps you and can figure out a wiring diagram for it and all. Lemme know, thanks.

All you have to do is google for the pinouts for a PCM with that service number or a '99-2000 truck. Here is one that poped up but I did not have time to read thru it all.
