That applies more to your car and the ECU. If you don't get a 99-00 Civic Si ECU to operate that motor(and wire up Vtec) you'll need to order a jumper harness and get a socketed and chipped ECU. You would order an OBD2b to OBD1 harness to run something like a p28 or you could go with a p30 or p72 as well.how I know it's OBD2B
well tomorrow I go check and I try to see that on the block.thanks menJust look at the engine code etched on the block. If it says B16A3 then it's OBD2A, if it says B16A2 then it's OBD2B
