MPI Conversion

Thanks. Yes, I believe it was a 12v+. My overdrive uses an on/off 12v+ that is also switched by a 4th gear pressure switch inside the transmission. It activates a open/closed solenoid inside the transmission. I think the wiring is the hardest part of the swap. There sure are a lot of wires when you first look into this swap. Everything else pretty much bolts right in with the exception of a few minor chassis mod's to fit an overdrive transmission.

Do you guys reprogram the ECM's too? It's amazing how well they work on high performance engines.
