It supports a broad range of diagnostic and programming tools (for example Maxisys family and many X431 and Tablet tools) and is intended for use on FCA vehicles equipped with the Security Gateway Module.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles require this 12+8 cable to communicate past the Security Gateway?\u003c\/h3\u003e\n\u003cp\u003eMany FCA model years introduced the Security Gateway Module (SGM) which blocks direct scanner access through the OBD port. This cable is required for models that route module connections through the SGW and list specific model-year ranges for bypassing that route. Always check the vehicle year and SGW presence before attempting connection.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2013+ RAM Promaster series\u003c\/li\u003e\n  \u003cli\u003e2015+ Fiat 500X and RAM Promaster City\u003c\/li\u003e\n  \u003cli\u003e2016+ Jeep Renegade; 2017+ Alfa Romeo Giulia, Jeep Compass and Cherokee\u003c\/li\u003e\n  \u003cli\u003e2018+ broad coverage: Wrangler (JL), Ram trucks, Dodge Durango, Journey, Charger, Challenger, Grand Cherokee, Chrysler 300 and Pacifica\u003c\/li\u003e\n  \u003cli\u003e2019+ most FCA models; 2020+ all FCA vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and use the CTobd 12+8 adapter with my scanner?\u003c\/h3\u003e\n\u003cp\u003eInstallation is a straightforward four‑step process that requires locating and disconnecting the SGW module’s 12‑pin and 8‑pin plugs, then inserting the adapter to bridge them to your scanner. This creates a direct path for the diagnostic tool without modifying vehicle wiring permanently.
