ok so i have a 97 integra LS its of course obd2a, well i just bought a b16a2 from a very cool person on this board(had to drive 300 miles but for 600 bucks i cant complain) my question is what harness would be best to use? he gave me the obd2b harness but im not sure if it just plugs up or not....what will i have to swap out if anything??? i have an obd1 gsr ecu and the conversion harness but what else will i need??? thanks guys the only reason i ask is because when i had a b16a2 in my eg hatch i used the obd2a gsr harness and it plugged in perfectly like the faq said.

 

it is a direct drop in and bolt on. except on the driver side motor mount bracket on the b16 engine . u can swap that bracket with your LS and then u can reuse all your LS motor mounts, rear t bracket.shift linkage , axles.and everything .even the LS throttle cable. and p72 ecu wont work because air and fuel ratio is different.u can get a chipped p28 ecu or p30 or p05. or get that p72 ecu chipped and u can reuse exhaust manifold and down pipe from your LS and it will bolt right on to b16a engine and your cat convertor

 

thanks man, hopefully ill see my baby back on the road tonight
