I have a 4L80E in my truck(91) but I'm swapping in a 5.3 liter, ecm and wiring harness from a 2000 chevy 1500. The ecm has been reflashed for a 4L80E but I can't find the correct wiring info and pin out locations for the tranny swap. Does anyone have access to this info?


Thanks


EDIT the harness is for a 4L60 I think
