Swapping a 1997 4.3 for a 2000 4.3 into a silverado
I bought a 1997 Silverado with a 4.3 and 4l60E that has issues with the trans and motor. I bought a 2000 4.3 and 4L60E trans with computer and wiring. The problem I am having is I think it would be easier to use the 1997 harness since there is no fuse block on the 2000, but I want to use the 2000 computer. I see there are some differences in pinouts on the computer, but I haven't found a good wiring diagram for the 2000. I have made a spreadsheet so I can compare pins. I am looking for a diagram similar to the one attached for a 2000 Silverado 1500 with a 4.3. Any other help here is appreciated.
