ECM Question


New Member
Hello all!

i have a 2000 EX that I’m finishing up a manual swap on, but I need help with the ECM.

A guy I know gave me his P2P ECM that we thought would work, but when I got the one out of my car I noticed a problem. My ECM, 37820-P2P-A92, makes use of the “D” connector and the new one does not.

The one he gave me is a 37820-P2P-A12.

Can someone please tell me what part number ECM I need?

Your old ECU is for a car with a A/T, the one your buddy gave you is for a M/T car. When you do a auto to manual swap, you should have read up that you should change ECU's also.
