i was told all i need is just a jumper harness or a obd1 ecu

why would u use a jumper harness, waste of money and time. just be sure that ur throttle body is obd1 and ur engine harness is obd2. u can use everything on ur motor, considering ur motor came with all obd2 parts(alternator,distributor,injectors), with ur obd2 engine harness and it will be plug and play. for the extra wires hanging around, just try to hide them. you can use a obd1 p72 ecu.

ur gonna need to change the manifold as well, cause obd2 evap purge control solenoid is different from obd1.

I dunno what the guy above me is talking about changing the manifold and crap to get it to work, he's just blowing it out his but.....

Yes, You just need an OBD1 ECU, as the 94-01 integra engine harness's plug right into EH/EJ's.

So pickup a 94-95 P72 *IIRC its a P72* ECU and plug it in and enjoy.

I have a 1996 OBD2 LS swap in my 1992 EH , the intake manifold, and all sensors are all still OBD2, my harness plugged right in, and I dropped a PR4 OBD1 ECU into it and it runs like a champ with no CEL's.

94-01 integra swaps are just 'plug and play'

ur throttle body won't work, u'll need obd1. it has the extra nipple for the canister.
