What year is your ITR? What year is your motor? Any modifications to the engine harness? Any mods to the ECU?

The OBD service connector will only work with the same OBD ECU. IE: A '97 ITR OBD connector will only work with a OBD2a ECU.

I am not positive if the service connector will work with a JDM ECU either.

The JDM ECU's do not have the OBDII service connector plug electronics in them. You must run a USDM ECU for the OBDII service connector to work. Also, if you have a JDM motor you will not be able to run the USDM ECU without adding a VTEC Oil pressure switch on your VTEC Solenoid and a CKF sensor on your oil pump. The JDM ITR motors do not come with these sensors.
