I've been working on this '97 Dak sport ext cab 4x4 since may of '11 and I'm to the point of desperation, almost. Bottom line, I need an engine wiring harness for the truck with the 5.2L. I cant use the VIN from the stock truck because I have transplanted a 5.9L with the 46RE tranny in place of the V6 and 42RE, plus the dealer tells me they no longer manufacture the 5.2L engine harness. I had used the V6 harness after adding the two additional injectors and it did start after the transplant but failed soon after due to the brand new oil pump failing. It turns over but no spark since the re-installation of the motor. Its now been at the dealer for service for 7 weeks. They cant seem to figure it out. Does anyone know of where I can pick up a good harness? I have tried the local pick-a-parts and the junk yards but no one has one. Thanks for anything.
