I'm trying to swap out my engine and hit a nasty snag. The 04 truck I have, won't match up to the wiring harness of the 05 engine I'm putting in it. So my question is this: Can I use an 04 engine harness with an 05 engine? Or would I be better off pulling the body harness from an 05. Or does someone make an adapter for the 05 engine harness to the 04 body harness(yeah right).
