I bought a b18c1 from a 2000 integra to put into my 93 si, and i want to use the obd2b ecu that came with the engine... what wiring harness do i use ? the stock harness or the gsr harness? do i have to wire in a 2nd o2 sensor to my ecu? do i have to do the CKF bypass trick and the VTPS trick? ive searched everywhere on different forums and everyone seems to have a different answer... no forum is about this EXACT swap so its hard to peice all the info together. I have the distributor harness jumper, alternator plug jumper and the ECU jumper harness to run the OBD2B ecu. I just need to know what else i have to wire in/change.

any help is much appreciated, thanks!!
