    I'm swapping a OBD2A engine into my OBD2B car and i'm using the ecu jumper. My question is i can't find my M/T ECU for the new engine but i have a A/T ecu laying around for the same year engine. My question is will the A/T ECU work even though im using a M/T engine and harness which doesn't plug into the A/T connector on the ECU.

    It will run if you get the three main connectors plugged in. You'll throw Automatic Transmission error codes.

    So CEL will be on until i get the right one? But will it idle correctly?

    Yes, getting the proper ECU is always the answer.

    Possibly. The ECU will make changes when a CEL is present, so I can't say for sure. Normally on OBD1, it would.
