PARANNIC SGW Security Gateway Bypass Cable 12+8 for FCA Chrysler Dodge Jeep RAM — Plug-and-Play OBD2 Diagnostic Adapter

PARANNIC's 12+8 SGW Security Gateway bypass cable enables direct diagnostic communication with modern FCA Chrysler, Dodge, Jeep, RAM, Fiat and Alfa vehicles without permanently modifying the vehicle’s wiring.

This compact, plug-and-play diagnostic adapter provides a temporary Security Gateway (SGW) bypass so diagnostic tools can access vehicle modules that are otherwise blocked by the factory security gateway. Built for reuse and compatible with many OBD2 scan tools (including XTOOL), the cable offers flexible construction and stable signal transmission to read and clear fault codes across late-model FCA platforms.

How does this cable let my scan tool talk to locked FCA vehicles?

The cable reroutes the diagnostic connection around the vehicle’s Security Gateway Module, creating a temporary pathway that lets your diagnostic device exchange data with electronic control units. It acts as an interface adapter rather than a permanent wiring change, so you can plug in only when needed.

• Bypasses the SGW to enable communication with restricted modules.
• Compatible with many OBD2 tools, including popular XTOOL units.
• Temporary connection—no cutting or splicing of vehicle harness required.
• Supports reading and clearing diagnostic trouble codes on late-model FCA vehicles.

Which vehicles and diagnostic tools are supported?

The adapter is designed for FCA group models—Chrysler, Dodge, Jeep, RAM, Fiat and Alfa—especially those that implement a Security Gateway. It works with a range of OBD2 diagnostic devices; verify compatibility with your specific tool before use.

• Intended for FCA group late-model vehicles with SGW protections.
• Works with multiple OBD2 scanners and diagnostic platforms.
• Recommended to confirm tool compatibility (contact PARANNIC for verification).
• Not a vehicle-specific permanent harness—universal approach for many models.

What are the build quality and practical features?

The cable uses durable materials engineered for flexibility and repeated use, delivering stable data transmission during diagnostic sessions. Its plug-and-play design keeps installation simple while minimizing wear on vehicle connectors.

• Flexible, durable jacket that resists kinking and everyday shop handling.
• Stable electrical transmission for reliable diagnostics and code clearing.
• Reusable—designed for multiple diagnostic sessions without permanent fitment.
• Compact, easy-to-store design ideal for mobile techs and repair shops.

How do I use it safely and what support is available?

Install the cable only when the ignition and diagnostic tool instructions recommend it, and follow your tool’s guidance for SGW bypass operations. PARANNIC offers a 36-month coverage period and customer support to confirm part fitment or troubleshoot fit questions.

• Follow your scan tool’s SGW bypass steps; avoid unsupported procedures.
• Confirm the cable matches your vehicle and tool before purchase.
• PARANNIC provides 36 months of coverage on products and customer help.
• Contact support for part verification if uncertain about fitment or compatibility.

Who is this for? Automotive technicians, independent mechanics, mobile diagnostic specialists and DIY-savvy vehicle owners who service late-model FCA vehicles and need temporary, reliable access to modules blocked by the Security Gateway will benefit most. If you require a non-permanent solution to read and clear faults across Chrysler, Dodge, Jeep, RAM, Fiat and Alfa vehicles—and you use an OBD2-compatible diagnostic tool—this PARANNIC SGW 12+8 bypass cable is designed to streamline those diagnostic tasks while protecting the vehicle’s original wiring.
