Hi guy just bought an 98 ek2 civic hatch and was considering putting my jdm integra type r engine in it. I have a p73 ecu and was wondering if I got a pre facelift ek9 harness if it would work with the p73 or will I have to get an adapter harness. Thanks
 
Yes it will work ! 100% pre facelift ek9 harness is OBD2a and so is a DC2

deffinately not.

what year is the vehicle the ecu came out of(p73) as anything after 95 obd2 onwards have immobilisers in the ecu.

your best option would be to use a p28 or p30 ecu with a obd2a - obd1 conversion harness.

also check the alternator plug on the ek9 harness as they are a 4 pin connector and some alternators on other models are 3 pin
