oops. my bad. didnt realize that it was concerning a motor.

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.
