I need help I'm doing a b18a1 swap to my 91 civic I have si engine harness but left side won't plug up:(
 
is it a dpfi engine harness ? if so the plugs are different on the driver side, sounds like you need to do a dpfi to mpfi conversion, and dont butcher the si harness, cut up a obd0 ls harness for what you need, the ef si harnesses are getting hard to come by
 
What sub model do you of the civic? If its a dx look into the dpfi to mpfi swap. I think a std hatch has to follow the same swap. You will probably need an ecu adapter. I haven't messed with an ef in like 10 years so I forgot a lot.
