Well you have and obd1 ecu. ALso the 3 wire idle air control valve setup will have to be rewired as well to a 2 wire setup to run the car correct.

[junior602]

your stock harness is an obd2b depending on the yr of engine an ecu would best describe to me wat u would need to do next find out those 2 questions for me meaning the yr of ecu and yr of engine and from there i can help u get your kar running correctly

CHASSIS year is what determines 2a or 2b, not engine, not harness, etc.
99-00 civic is 2b. 00-01 integra is 2b. that means you need a 2b p75. but you will still have to modify the idle air control (IAC) from 3 wire to 2 wire, simple enough though. i may even have one of these ecus laying around since most go back to obd 1 and then ecu can run any engine since they're fully programmable.
