So im pretty sure i know the answer to this.. but wanted some opinion.. I have an automatic 2.2 im swapping into my loyale. I'm leaving the manual EA transmission in the car and using an adapter plate. Was planning on using the same wiring harness and ECU(for the auto). Now im wondering.. am i gonna need a new ECU(and/or harness)? I know with the honda civic computers you can modify the board so its manual if it was originally automatic. i figured the automatic harness would just have extras. Thoughts anyone?

Check pin B48 on the ECU (AT/MT Identification). I think it's open for MT and grounded for AT. Same harness and ECU should work fine for either type of trans. Just about everything you need to know is in the EA2EJ.pdf file that is floating around somewhere.
