Hey boys! I have a bit of a problem here, I swapped an 88 350 / 5 speed into my 94 k1500 4x4. The truck originally had a 4.3 / 5 speed. Problem is the harness that came on my 88 engine won’t work with my truck as all the plugs are different. One of my friends has a harness and computer that’s the same but it has an auto transmission. Will the ecu work in my truck? Thank you guys I’m terribly confused haha.
