im kind of new to hondas and just recently aquired an eg hatch with a d15b7. i heard that the b18b1 is plug n play to the obd1 harness i have in my eg if its the 94-95 b18b1 with the obd1 harness. the one i just bought is a 96 with and obd2 and i was wondering if i can still use the obd1 and what i would need to make it work?

 

since u bought an OBD-2 motor swap, all u have to do is splice the OBD-1 injector clips and alternator clip onto your harness. You also may have to splice the distributor. Thats about it.

 

Did your B18B1 come with engine harness? If so, just plug it in to your shock tower plugs and call it a day. If you didn't get a harness, try and find a obd2 integra harness to save you from having to cut and splice injector, distributor and alternator plugs.
