so long story short i have to pull motor out of my 1993 integra because i snapped the subframe and shell is rusty anyways, i picked up a rust free 91 shell that had the motor and tranny pulled. the 1991 still has the main harness but no engine harness.
Question is will my b18 from the 1993 just hook right up or do i need a Obd1-obd0 jumper harness?
What else would i need?

thanks

 

just bought a rywire obd0-obd1 jumper harness.
is there anything else that i am going to need?
please help thanks

 

I think you need to ecu from the 93 also.

 

ya i planned on useing the ecu fromthe 93 thanks, i just didnt know if there if i have to pull the main harness out of the 93 and use that as well.

Will the 1991 main harness hook up to the 1993 engine harness with the rywire jumper harness? im just confused on what exactly the jumper harness is going to hook up to

 

Im pretty sure the jumper harness just lets you hook the obd0 engine harness to the obd1 ecu.
Id think the plugs would still hook up to eachother between the engine and main though. Not 100% sure but I don't see them changing the harness too much between years.

 

if you have the obd0-obd1 you should be fine.

 

Also if you check on G2Ic.com they have more info on this since thats all they mess with 90-93 integra da's
