94blkHB

So i have a 94 Civic HB and im swapping the d15 out for a d16a6 out of 91 CRX what will i have to do about the wiring because the Civic HB is obd1 and the CRX is obd0?

You'll need to run OBD-I injectors so the plugs match up, chop the end off your OBD-I dizzy and use a dizzy match diagram to match it to the OBD-0 dizzy wire (so you can plug the CRX dizzy into ur harness), and you'll need an OBD-I to OBD-0 conversion harness so the ECU plugs right in - you can pick one up used or at jdmshit.com.

Dizzy plug rewiring diagram:


Basically all you have to do is solder/crimp the BIG white wire from the dizzy onto the yellow/green wire of the harness. Everything else is just same color matching.

I'm 95% sure the mounts, linkage, are swappable, but I'm not positive. Not sure about the driverside mount, they changed it from OBD-I to OBD-II, not sure if OBD-0 was diff.
