Where can I go for harness modifications

If you don't want to swap or modify the ECM, then forget trying to put a TPI intake on the truck. At teh very least a new tune and some hardware modifications to the MEMCAL WILL be needed to make it run correctly. You can't just swap the intake manifold and expect it to run right.

I understand this and have a spare ECU and prom I'll start on soon
