I have a 92 Civic with a B18B swap in it already. Im getting a 97 B18C1 complete longblock OBD2 dizzy and alternator. Can I still use my harness thats already in there or do I need the OBD2 harness & plugs? Im going to be using a OBD1 GSR ECU. Whats need and how do I go about wiring in VTEC (if not already cuz its a 92), knock sensor, IABs etc etc? Any help is appreciated. Thanks.
