we have an OBD1 motor (92 GSR) in an OBD0 chassis (integra 89). The harness connectors at the firewall don't mate.
We are planning on running an OBD1 p72.
Can anyone direct me to any thread on how to solve this dilemma.
Any help is much appreciated.

I've not seen a B18C1 swap in the pre 90 Integra's so have you done any research? I'm not aware of a mount kit for the motor in that chassis, not to say that there isn't one.
But to cover your Q's about OBDI in an OBD0 chassis, basically you need to transfer the OBD0 harness onto the B18C1. You will need to lengthen, shorten, and add some extra wires for the VTEC solenoid, VTEC pressure switch, knock sensor and IAB. You will also need to rewire the injector clips and distributor plug. After that you could purchase an OBD0 to OBDI conversion harness and the ECU will plug in without any extra wiring.
You will not need an injector resistor box if you plan to run the complete OBDI motor with the OBDI injectors and ECU.
