PARANNIC SGW Security Gateway Bypass Cable 12+8 for FCA Chrysler Dodge Jeep RAM — OBD2 Diagnostic Pass-Through, Reusable Workshop

PARANNIC's 12+8 SGW security gateway bypass cable enables direct diagnostic communication with FCA Chrysler, Dodge, Jeep and RAM vehicles that use the Security Gateway Module.

If you work on late-model FCA vehicles, the factory Security Gateway can block aftermarket scan tools and programming devices. This PARANNIC cable provides a temporary bypass of the Security Gateway so diagnostic tools can talk to vehicle modules, read and clear trouble codes, and perform diagnostics without permanently modifying the vehicle. It's a plug-and-play harness built for repeatable workshop use and compatibility with a wide range of OBD2-capable scanners.

How does this cable let my scanner access vehicles with the Security Gateway?

The cable reroutes communication lines around the Security Gateway Module, providing the required pins and signal paths so your diagnostic tool can establish a session with module ECUs. It acts as an adapter between the vehicle's 12+8 connector and standard OBD2 diagnostic equipment.

• Routes required CAN/LIN signals to the diagnostic tool.
• Mates 12+8 FCA connector to standard OBD2 pinout.
• Works as a temporary bypass—no permanent vehicle wiring changes.

Which tools and vehicle models are supported with this cable?

PARANNIC designed the harness for the latest FCA platforms that use 12+8 connectors—covering many Chrysler, Dodge, Jeep, Fiat and Alfa models. It is compatible with most third-party diagnostic devices that use the OBD2 interface to read and clear codes.

• Compatible with multi-brand scan tools and J-2534 devices that support OBD2 diagnostics.
• Works on FCA models employing the 12+8 security gateway connector.
• Confirm your vehicle's connector type before purchasing; contact PARANNIC for verification.

What are the build and performance features of the PARANNIC bypass cable?

The cable is built for workshop environments with flexible insulation, solid contacts and a stable transmission design to reduce communication errors. It's reusable—plug in when you need to diagnose, unplug and store when finished—so it doesn't require permanent installation in the vehicle.

• Durable materials for repeated use and improved cable life.
• Secure locking connector and stable electrical contacts for reliable data flow.
• Plug-and-play operation; no tool-specific programming required.
