engine wiring harness

Post by slammed98gmc »

Im looking to buy another engine wiring harness to modify for my engine swap.(attempting to do the swap on my next 3 day weekend) . Im having a hard time finding one for a 2001. Ive got a line on a 2003 zr5 harness and pcm and I was wondering if anyone knows if there is a difference in wiring harnesses from a 2001 to a 2003?

I would think there are differences. The EGR system is different. The Fuel injectors differ. Those I know for sure, there may be more.

The injectors may not matter, as the differences are internal to the manifold. The EGR valve , or lack thereof on the latter may be a problem.

Call your local dealer and get part numbers. If they have different part numbers, they are likely different.
