gotta convert your oil pump to obd II, it has the crank angle sensor there or if you don't want to covert the oil pump then you can bypass the sensor at the ecu.

change alternator to obd II since plugs are different or you can convert the the stock harness to use the obd 1 alternator.

obd II distributor or convert the obd 1 distributor

change your alt dizzy injectors to obd2 and do the trick on the ecu

alright so i use my obd2 ex wire harness and extend wires onto obd1 b18b1 and cutt & connect injectors, switch out alternator plugs, rewire dizzy, and trick the ecu for the crank sensor, basically wiring the obd1 motor to everything to obd2 wire harness and i could run my obd2 ex ecu for the mean time correct until i get a obd2 p75. if so then im gonna start on it.

you dont have to take of your oil pump ther should be a spot for the sensor to screw into if its obd1 oil pump buit if its a obd0 oil pump then yes you will have to replace the oil pump also you are going to need a knock sensor and hope you do it right i didki it with my obd1 b20/vtec in a 99 obd2 hatch and i pass emissions
