Probably the one we did....we spent about 6 hours re-pinning the harness to work. The OBD2(b) harness is different under the dash. I can't remember all that was involved, because we did 2 that month (Obd2b motor's and ECU into obd2a hatchs....and the other one was also an auto-5spd swap at the same time.)

Take a GOOD look at the ECU connections, and compare them. notice where the wires run (into the engine bay or under the dash). You won't notice electrical tape or anything like that, we literally re-pinned the harness plug, one wire at a time.

That's my only concern.
