use your harness, your distributer and everything else OBDO take only the engine, not even the tranny. use yours, it's good. also you will need to get a VAFC(vtec controller) to engage your vtec.(you use your ECU and the VAFC engages VTEC) or you can use the B16 PR3 OBDO ECU.(trust me you can do this and it will work) other then that it straight forward. you can't use his Fuel injectors either.

You could also wire for obd1 and use the p28 ecu. This would give you somewhat better fuel curves. But leaving it obdo would be the easiest way.
