This it a good read for you:How ECUs Use Closed-Loop Controls to Make Fueling Corrections v1.02 - Mazda Forums Comments regarding your Uncle & associate were meant solely for your entertainment. Being pissed at them seems to distract your train of thought. You might want to run any plans to put em out of their misery by Gramma first. She might want you to put off till after the holidays. Grammas are like that!

Mass air trucks are more common from '94 on but I'd say the vast majority of these had the E4OD tranny, and that presents problems when transplanting the system into a vehicle with a non computer controlled tranny. Luckily all OBD-1 Ford systems use the same computer connector and the same pinout for the most part, so you can plug a V8 mustang computer into a truck harness, and with only a few wiring changes and additions have a fully functional SEFI system. The truck harness is still a good candidate to get the extra wiring needed but it may not be a direct plug-in swap, on the '80's trucks you will most likely have to strip the MAF and injector wiring from the donor harness and add it to the existing.
