There are some real good wiring diagrams for the ECM over at gnttype.org. I printed them off and used that when I did the swap into an '87 Iroc a few years back. Good idea on the painless wiring boss, used that for the Tuned port I just did in my el camino.

Post some pics of the chevelle? I would like to see them some time. Also what wiring harness did you go with for the main harness for the chevelle. I'm got the caspers harness for my engine. I've got to get a full harness for the car itself, since i'm doing a ground up on the car.

I dont plan on selling mine anyways. I just got my power steering line made the other day,did not cost that much(20.00bucks). Does your car come with any options(p/s, p/b, air). Are trying to stay mostly stock stuff?
