    Question

    Besides the ECU, what else is needed for the conversion. I'm trying to put a 97 GSR into a 93 Civic.

    Use the 1993 Civic wiring harness and all you need is the OBDI ECU...easy enough.

    You will need an adapter harness to plug the 97 ECU (OBD2) into the 93 harness plugs (OBD1). They are usually about $250.
