Im swapping a 98 b18b1 into my eg hatch, Previously i converted the integra onto OBD1 with the obd2-obd1 conversion harness and an OBD1 ECU.

So my question is, will the ecu plug into the civic harness and wont require no extra wiring?

I wont be needing Vtec wire since i dont have Vtec, and i wont be needing O2 sensor since mine is run off the map. So it should plug and in start right up?

 

if its obd1 then the ecu will plgu right in

 

as long as your ecu is obd1 its plug n play
