ok i know this has been coverd here and there...but need straight forward answers....so i got a obd2 b18b and am going to convert to obd1 so i will need the p75 obd1 ecu and the conversion harness wat else is needed? distributor from obd1 ls? and..theres gotta b more right?

 

4 wire o2 sensor and if your going from obd0 to obd1 u can eliminate the resistor box and run obd1 injectors but if u stay obd0 u can run the injectors with the resistor box

 

sorry is the motor obd2 as well as the car..if so u just need the jumper harness and the ecu...because if ur car is obd2 the obd1 ecu will only look for one o2 sensor and the crank sensor is located at the pulley on the obd2 so u can just unplug it and it will b in the dizzy of the obd1...

 

 

yea motor is ob2 car is ef obd0
