Ok, I built a B20/VTEC for my 93 Civic ex coupe, but now I bought a stock 98 DX hatch. I have been searching the internet on how I can swap this motor in, but everyone seems to have their own ideas/opinions about this swap. Since I am going to use a Hondata OBD1 ecu, couldn't I use the OBD1 motor's wiring harness with an OBD2 to OBD1 ecu harness? I am going to use all of the sensors/plugs from OBD1 anyway, and it would save me from having to modify my injector plugs, or swap them out for OBD2 RC's, or get a new distributor. What mounts do I need to use? Thanks for the help!

the 96+ civics have a 1 piece harness that goes all the way to the ECU the pre 96 civics use a 2 piece harness that connects at the shock tower .... just solder the OBD-1 plugs on the OBD-2 harness then use the addapter to plug it into the OBD-1 ECU... no problem :)
