I am working on rebuilding the vehicle listed above into an off-road vehicle. The fuel tank was gone when purchased and someone had cut off the fuel pump wiring harness. We found a donor tank with fuel pump installed, but the wires had been cut right at the connectors to the fuel pump and are unmarked. is there a wiring diagram that shows what colored wire goes where? Thanks!

Hi,

If you look at the attached pics below, I attached the entire powertrain management wiring schematics. I added all of them simply because it sounds like they may be helpful.

If you look at picture 6, I highlighted the fuel pump. Also, I cut each of the pics in half to make them more readable. I did overlap them to make it easier to follow.

Here is a link you may find helpful:

I hope this helps. Let me know if you have other questions.

Take care,
Joe
