I was wondering.Im sure it has been done but....I have a 98 Civic hatch and I got a b16 b for it.Now after intalling and bolting everything up,I noticed the engine is a 2000 and the car is a 98 .So is the PCT ecu(98).Next is the question.Can I use the original wiring harness(civic) that matches obd2a?Or do I need to convert to obd2b.The harness of the car has 3 ecu plugs and a green one. The b16b harness has 2 ecu plugs and a green plug.
