ohhh ok I see now. Well since everything is OBD2 meaning the cars original harness that's connected to the ECU, which should be an OBD2A and you're using and OBD2 GSR ECU, I think that if your looking for jumper harness you may be searching for an OBD2A to OBD2B harness. That is if the ecu doesn't plug into your current ECU harness
