ditch the obd2 engine harness, use your original harness.
then u can either use obd0 ecu and distributor, or use a obd-2 distributor with preferably a obd1 ecu using a jumper.

Re: OBD2 LS into a 90 CRX DX (capbyrd)

I have a 96 B18B1 in my 91 CRX DX. You will need to reuse your stock engine harness and rewire from DPFI to MPFI which is not as hard as some people make it out to be. I used all OBD0 components to make things easier: 91 Integra LS PR4 ECU + distributor, 90 CRX Si fuel injectors + resistor box and a 94 Integra GSR alternator (OBD1 is same as OBD0 plug style).
I used a 92 YS1 GSR cable tranny and HASport mounts and shift linkage. The car was originally an auto so I has to wire around the interlock and wire up the reverse lights. Other than that it was pretty much a straight forward swap.
