A simple, easy to install solution to adding an OBD2 port that bypasses the Security Gateway on most FCA vehicles.  Simply snap out your factory OBDII connector from its bracket, and snap in one of the female OBDII connectors from this harness.  This gives you an additional OBD2 port right behind the factory port that’s not blocked by the security gateway.   The port cannot communicate with the radio using this harness so if you are using a Tazer, Navigation In Motion and TurnCam won’t work.
