I know there has to be a post out there somewhere but would take forever to research.. I have a 1992 Civic VX Hatch and did the D15Z1 to D16Y8 conversion,, runs as it should and with help from many on here I was able to get the proper pieces that I needed to get the project done,, I have one issue left and keep running into a wall on research to fix the problem,, I have a code 41 for the O2 heater and have seen where i may need to rewire the O2 sensor into a 4 wire system., Anyone out there actually have this diagram or what wires get moved to where thanks
