ok guys, im doing a b18b1 swap into my 92 cx. i read that the integra engine harness is a direct plug and play into the shock towers. im just wondering though since the shock towers are obd1 if running the obd2 ecu will be a problem? i know i have to get a jumper harness. right now the car has a d15b swap with p08. should i just run the po8 or will the p75 not throw any codes, or minor ones if any? basically im just wondering if the civic cabin harness has all the wires there to properly run the obd2 motor or if i will have to add any wires etc... any help is appreciated, thanks.

 

you wont be able to run a obd2 ecu without a ecu conversion harness. And even still, your setup will run like ****. You might as well go to the junkyard and take a obd1 ls ecu out of an integra.

 

save the money you would spend on the harness; sell your p75,
and buy a obd1 p75 for $40-$50

plus adam b16a is right. It will still run like shet and throw unecessary codes
