    Hello everyone my son and I are putting a truck together for him and here is my situation I bought a 93 gmc extended cab 2500 4x4 with a 5.7 and a 4L80e we replaced the cab with a 94 Chevy 1500 that had a 5.7 with a 4L60e we also used the 94 wiring harness but now I have an issue with the wiring configuration at the trans as far as speed sensors and tranzoa controls not sure what to do here hope someone can help thanks in advance Jim/josh

    You need to use the wiring harness and PCM from 93. The 4L60 harness is entirely different.
