and it comes with the b18c harness. I have a 97 civic EX (no vtec). I shouldn't have to use any of my old EX wiring right? except for whats under the dash right? is there such a thing as an OBDII to I conversion harness so I can hook it right into the wiring under my dash, as I will be usign the ECU for the B18C of course....
