I have read the previous post and have a couple things I would like to clear up. I got a complete B18A OBD-0 for free and a '94 Civic CX. I would like to keep my car OBD-1. If I change the distributer and ecu to one from an OBD-1 car would that be all I have to change? I would not need any harnesses of some sort do I because I can just use my old harnesses? What about O2 sensor? I was told to use a 4 wire o2 sensor which car would I get one of these from? The motor would bolt up just as if a B18B would?
