I say this because the wiring diagram really does show different pins for the connector for the OBDII.
I don't know if it works or not, but the fact that My JDM ECU connects fine via the USDM body harness OBDII and responds well to tactrix, is not indicative that the pins are right for it in the JDM OBDII configuration.
