    Hey guys I was just wondering if anyone knows the difference between the JDM B16a engine harness and USDM B18a engine harness. I am in the process of a swap and used the JDM harness, only to find out they are slightly different. The only problem I found is near the resistor box there are 3 plugs on the USDM harness and on the JDM there are only 2, but on the passenger side of the JDM harness there are 3 plugs where there are only 2 on the USDM. The plug on the near the resistor box in question is a smaller 5 pin plug. The extra plug on the JDM harness I am assuming is the VTEC and 2nd o2 wires.

    Thanks,
    Josh

    P.S. Its a first gen B16a going into a 1991 Integra Ls

    Problem solved just reused the Ls harness. The third plug was something to do with the fuel pump.
