Thank you Paul. I couldn't have started this if it wasn't for you help and previous help. I'm going to adapt the '86 harness into the '84 Mustang because that's what I have (and the '84 Mustang will stay speed density) but I think the Fairmonts would be easier to use the FRPP harness which went obsolete along with the other two supporting harnesses - now I need to figure out how to make my own Oxygen Sensor Harness for the '91-'93 Mustang.
I think I saw somewhere the difference between the two harnesses in regards to the type transmissions is one pin or the other is used on the main plug depending on trans type.
I also read over at the Ford Fuel Injection .com sight that their harness is better than the new FRPP harness. I don't like the new FRPP harness, it sticks the TFI and SPOUT connectors on the end of one of the fuel injector wiring and without the salt and pepper connectors would make engine removal tough.
Okay, I'm babbling. I'm probably tired.
