Will my harness work with a truck (747) ECM?
I'm asking this because I was considering using the Edelbrock TBI-to-multiport setup. Apparently, all I need is the truck ECM. Is this true? What other changes would have to be made? Thanks.

I know Pablo did the change over to a 7747 ecm with his TBI system. From what I've heard it's the same as the 8746 that came in the cars. There are just a few things different, I think the 8746 has a hack out that lets you tune even more stuff.

This is really a good question for the PROM board.
