Autel 12+8 OBDII Bypass Cable for FCA SGW Vehicles (80 cm) — Restores Full Diagnostics & Coding

The Autel 12+8 cable is a plug-and-play OBDII adapter that bypasses FCA Secure Gateway (SGW) on compatible Chrysler, Dodge, Jeep, Fiat and Alfa Romeo vehicles to enable full diagnostics and module coding without recurring AutoAuth fees.

This adapter provides a reliable physical bridge between a vehicle’s factory 12-pin and 8-pin SGW ports and a standard 16-pin OBDII diagnostic tool. Designed specifically for FCA vehicles from 2018 onward that include Secure Gateway modules, the Autel 12+8 cable restores access to bidirectional controls, service procedures and coding functions normally blocked by SGW. The cable’s extended 80 cm length, durable PVC construction and precise connector fit make it suitable for professional shops and advanced DIYers who need consistent data transmission and easier reach under dashboards.

How does this cable let my scanner access SGW-equipped FCA vehicles?

The Autel 12+8 cable physically connects the vehicle’s two factory gateway connectors (12-pin and 8-pin) to the diagnostic tool’s 16-pin OBDII interface, creating a transparent link that enables the tool to communicate with modules normally restricted by SGW. No software trickery or annual subscriptions are required; access is provided through the hardware interface.

• Connects both 12-pin and 8-pin vehicle ports to a standard OBDII 16-pin input
• Enables diagnostics, active tests, and module coding via your scanner
• Works on FCA SGW vehicles from 2018 and later

What makes this 12+8 cable different from stock adapters?

The Autel cable is longer and built with higher-quality materials to improve usability and lifespan. Where many factory-style cables are short and rigid, this adapter uses an 80 cm PVC jacket for flexibility and a precise connector design to ensure a snug, reliable fit with minimal signal loss.

• Extended 80 cm length for better reach and maneuverability
• Durable PVC insulation resists wear, oil and heat
• Secure mating connectors designed to prevent data leakage and jamming

How do I use the Autel 12+8 cable with my diagnostic tool?

Usage is straightforward: plug the 12-pin and 8-pin vehicle connectors into their respective ports, then attach the 16-pin OBDII end to your scanner or VCI. Ensure all connectors are fully seated. Once connected, run your scanner’s normal routines to read/clear codes, run active tests, perform service resets and access available coding features.

• Plug 12-pin and 8-pin ends into the vehicle gateways separately
• Attach the 16-pin OBDII to your diagnostic tool or interface cable
• Verify connections before running diagnostics, active tests or coding

Is the Autel 12+8 cable compatible with my scanner and vehicle?

The cable uses a standard 16-pin OBDII interface, so it is compatible with most professional and aftermarket scanners that accept standard OBDII input. It is intended for FCA vehicles that include Secure Gateway modules introduced around 2018 and later; check your vehicle’s service manual or dealer data to confirm SGW presence and connector layout.

• Standard 16-pin OBDII plug works with most scanners/VCIs
• Designed for FCA vehicles with SGW (Chrysler, Dodge, Jeep, Fiat, Alfa)
• Not a replacement for scanner software or manufacturer subscriptions beyond hardware access

Who is this for: Technicians, independent workshops and experienced DIYers who service FCA vehicles with Secure Gateway modules and need a durable, user-friendly hardware solution to restore full diagnostic and coding access. It’s ideal for shops that want to avoid recurring AutoAuth subscription costs and for owners who perform advanced troubleshooting, programming or module configuration using third-party diagnostic tools.
