Autel 12+8 to OBD2 Cable for Chrysler Dodge Jeep Fiat Alfa Romeo — 80 cm SGW Bypass, PVC Jacket

Autel's 12+8 cable is a plug-and-play programming adapter that bypasses FCA Secure Gateway (SGW) on 2018+ Chrysler, Dodge, Jeep, Fiat and Alfa Romeo vehicles to enable full OBDII diagnostics and module coding without recurring FCA AutoAuth fees.

This 12+8 to OBD2 adapter from Autel gives technicians and advanced DIYers a reliable, longer cable engineered specifically to work with FCA SGW-equipped vehicles. With an 80 cm length, durable PVC jacket, and precise pin mapping for the 12-pin and 8-pin Chrysler ports, it connects your diagnostic tool or VCI to the vehicle so you can perform bidirectional tests, read and clear trouble codes, and carry out service and coding procedures that are otherwise blocked by the OEM gateway.

How does this cable bypass the FCA Secure Gateway (SGW)?

The cable provides direct access to the vehicle networks by routing the diagnostic connection through both the 12-pin and 8-pin Chrysler connectors while presenting a standard 16-pin OBD2 plug to your scanner or VCI. It does not alter vehicle software; instead it allows authorized diagnostic tools to reach modules that the SGW would otherwise restrict.

• Direct 12-pin and 8-pin connectors for SGW-equipped ports
• Standard 16-pin OBDII plug that mates with most scanners/VCIs
• Enables diagnostics, active tests, and module coding where permitted
• Avoids repeated AutoAuth subscription for compatible tool workflows

What vehicles and years are compatible with the Autel 12+8 cable?

This adapter is intended for FCA-brand cars and SUVs that use the Secure Gateway architecture introduced around 2018 and later. It supports Chrysler, Dodge, Jeep, Fiat and Alfa Romeo models that feature separate 12-pin and 8-pin diagnostic ports alongside the OBDII network.

• Designed for FCA SGW systems from about 2018 onward
• Works with Chrysler, Dodge, Jeep, Fiat, Alfa Romeo models
• Compatible with scanners and VCIs that accept a standard 16-pin OBDII plug
• Check vehicle connector layout for 12+8 pin port presence before use

What are the physical and build features of this programming cable?

The Autel 12+8 cable measures 80 cm (about 2.6 ft) to give more reach than factory short adapters, and it uses a robust PVC jacket for abrasion and environmental resistance. Precision-molded connectors ensure correct pin alignment, low-noise signal transfer, and long service life in workshop conditions.

• 80 cm length for easier access to tool or laptop in workshops
• High-quality PVC insulation for durability and anti-interference
• Exact pin mapping to prevent misconnection and data loss
• Plug-and-play design — no soldering or tool modification required

How do I use the cable safely with my diagnostic tool?

Connect the 12-pin and 8-pin ends into their respective vehicle ports, then plug the 16-pin OBD2 connector into your scanner or VCI's main cable. Ensure all connections are fully seated and use diagnostic software or a compatible Autel device to begin supported functions; follow vehicle and tool manufacturer guidance for module coding and programming safety.

• Insert 12-pin and 8-pin adapters into vehicle ports securely
• Attach 16-pin OBDII end to your scan tool or VCI cable
• Confirm tool compatibility and software permissions before coding
• Disconnect power or follow specific vehicle procedures as directed

Who is this for: Technicians, independent shops, and skilled DIYers who work on FCA vehicles that use the Secure Gateway and need reliable access for diagnostics, active tests, services, and module coding. If you require a longer, workshop-friendly adapter that pairs with standard OBD2 scanners and VCIs to avoid recurring AutoAuth costs for compatible tool workflows, this Autel 12+8 cable is built for that purpose.
