Autel 12+8 to OBD2 Cable for Chrysler SGW Vehicles — 80 cm adapter for full diagnostics, plug-and-play

The Autel 12+8 cable is an 80 cm OBD-II adapter that lets compatible Chrysler‑group vehicles with SGW security modules connect to diagnostic tools for full functions without FCA AutoAuth subscriptions.

Modern FCA vehicles introduced the Secure Gateway (SGW) to restrict direct access from aftermarket scan tools. This 12+8 to OBD2 adapter from Autel provides a secure, vehicle‑matched connection that enables full diagnostics, active tests and module coding on SGW‑protected Chrysler, Dodge, Jeep, Fiat and Alfa Romeo models from 2018 onward. The cable is a plug‑and‑play hardware companion designed to sit between the vehicle’s factory ports and your diagnostic interface so you can access vehicle data reliably.

How does this cable let me perform full diagnostics on SGW‑equipped vehicles?

When connected correctly, the 12‑pin and 8‑pin ends interface with the vehicle’s gateway hardware while the 16‑pin OBD2 end connects to your scanner or VCI. The cable preserves signal integrity and routes necessary communication lines so supported diagnostic tools can run deeper tests and coding routines without subscription gates.

• Routes required SGW communication lines to your scanner
• Enables bidirectional commands, live data and code clearing
• Compatible with tools that expect a standard OBDII interface
• Works on FCA models from about 2018 that use SGW modules

Is the cable durable and practical for everyday shop use?

This Autel adapter uses rugged PVC insulation and precision molded connectors to hold up in workshop environments. The 80 cm length gives more reach than common short adapters, letting you position diagnostic tools conveniently while working on the vehicle.

• Thicker, abrasion‑resistant PVC jacket for workshop durability
• Secure connector fit to prevent intermittent data loss
• Longer 80 cm lead for easier tool placement and access
• Designed to resist electrical noise and ensure consistent signals

How do I connect and use the 12+8 adapter with my scanner?

Connection is straightforward: plug the 12‑pin and 8‑pin vehicle connectors into their respective ports, and attach the 16‑pin OBD2 plug to your scanner or VCI’s main cable. Confirm a snug fit, power the vehicle or ignition per tool instructions, then launch your diagnostic software to discover available modules and services.

• Insert 12‑pin and 8‑pin ends into the vehicle ports separately
• Attach the 16‑pin OBD2 plug to your scanner or interface cable
• Ensure ignition/vehicle power as required by your diagnostic tool
• Use supported software to perform scans, active tests, coding

Does this cable replace FCA AutoAuth subscriptions?

The cable provides the hardware path many diagnostic tools need to access SGW‑protected functions without repeatedly paying FCA online authorizations. Whether you’ll avoid subscriptions depends on the scanner and software you use; this adapter eliminates the hardware barrier so compatible tools can operate as intended.

• Removes physical access restrictions imposed by SGW ports
• Subscription avoidance depends on your diagnostic software policies
• Pairs with tools that implement local or token‑based authentication
• Autel support available for setup or troubleshooting

Who is this for: technicians, independent repair shops and experienced DIYers who work on FCA Chrysler, Dodge, Jeep, Fiat and Alfa Romeo vehicles equipped with Secure Gateway modules and need reliable, durable hardware to unlock full diagnostic, service and coding capabilities.
