swap the engine wiring harness as the plugs between the engine harness and firewall wiring harness are different.
i dont know if the B18C changed the timing (CKP, TDC) sensor locations from the distributor to the crank. if so, the easiest way to bypass this is to get an OBD I dizzy. if you cant, the OBD II timing sensors can still be read by an OBD I ecu... so you can just extend the wiries to reach the TDC and CKP sensors on the front of the motor.

i'm experiencing trouble getting my '97 gsr which was ODB-2 and is now hondata ODB-1 to be set with the correct timing (14BTDC) as i read your guy's speak i saw something about crank sensors and different markings for ODB-1 cars. i have accesory pully to turn the supercharger , but i'm fairly certain it was specified for my vehical (in its original configuration) are either of these things or others possibly the reason i can get 5-7 btdc with the dist slammed to the back of the car ?
Still here... sorta...

I have an OBD2 B18C1 in my OBD1 civic. All I did was use everything OBD2 for the motor except the ECU. I have an OBD1 P72.
I had to run the extra wires that my stock ecu harness didn't have (VTEC, VTEC oil, knock, and evap purge.. I think that was all). That's it. There's nothing to it.
