I have swapped engines and transmissions and am running into some questions for someone that has done it. Please let me know if you have.

The engine/tranny and wiring harness - ECM/ECU came off a 1995 and the car is a 1994. The reason I changed the harness was due to the transmission having a different park/neutral connector on it and the harness for the 4A-FE was different. There may have been other connectors that were different as well. Since the majority of changed parts were 7A-FE from a 1995 I was trying to keep it all 1995 compatible.
The ECM/ECU has three connectors on it and on the 4A-FE there is a 12 Pin connector whereas on the 7A-FE there is a 22 Pin connector. As Bitter has said - I may have a harness that is for an OBD2 car and not from a OBD1, but the harness is the same and it is the cars connection to the ECM/ECU that appears to be different. I don't know if the donor car is still at the junkyard, but I can check the connector on that car. It was a 1995. I took both the ECM/ECU and the wiring harness from the same car - but the cars internal wires must be different. I will have to check it out.
