X-OBD FCA 12+8 SGW Bypass OBD2 Cable for Chrysler Dodge Jeep Fiat 2018+ — Plug-and-Play, No-Wire-Cut

The X-OBD FCA 12+8 SGW Bypass OBD2 Cable lets compatible diagnostic tools communicate with 2018+ Chrysler, Dodge, Jeep and Fiat vehicles equipped with the Security Gateway (SGW) module without cutting factory wiring.

This bypass cable provides a direct, plug-and-play interface between vehicles that use the 12+8-pin SGW connector and a wide range of professional OBD2 scanners and software platforms. Built with high-purity solid copper wiring and reinforced connectors, the harness preserves signal integrity while avoiding permanent changes to the factory harness. It’s designed to help technicians and car owners access ECU data for maintenance, inspection, and routine diagnostics where SGW security traditionally blocks standard OBD2 communication.

How does this cable let diagnostic tools reach SGW-protected systems?

The X-OBD adapter creates a stable, authorized physical path around the vehicle’s Security Gateway so supported scanners can exchange data with vehicle ECUs. It does not require Wi‑Fi, subscriptions, or ongoing gateway unlocking—once connected the compatible device can communicate for the session.

• Bypasses SGW restrictions via the 12+8-pin factory connector without cutting wires
• Supports ECU communication for diagnostics, fault reading, and maintenance checks
• Works with scanner software that expects a direct OBD2 link to vehicle networks

Which vehicles and scanners will this bypass cable work with?

This harness targets FCA platforms made from 2018 onward that use the 12+8 SGW connector, including many Jeep, Dodge, RAM and Chrysler models. It’s compatible with a broad list of professional scanners and communication tools that are designed to operate through an OBD2-style interface.

• Supported vehicles: Jeep Renegade, Compass, Cherokee, Wrangler, Grand Cherokee; Dodge Ram, Durango, Journey, Charger, Challenger; Chrysler Pacifica, 300
• Compatible devices: Autel MK and MP series, MS and DS series, IM508, MS906 families and similar professional scanners
• Note: Requires scanner/software that supports full ECU data exchange via an external adapter

How simple is installation and will it affect my vehicle wiring?

Installation is plug-and-play and does not require splicing or altering the factory harness. The cable uses reinforced connectors and solid copper internal conductors to maintain consistent signal paths, minimizing the risk of intermittent faults or damage to vehicle wiring.

• Plug directly into the vehicle’s 12+8-pin SGW connector — no cutting or soldering
• Durable connector housings and strain relief for reliable repeated use
• Removable and reusable for shop workflows and mobile technicians

What kind of diagnostic workflows can benefit from this adapter?

Technicians performing routine inspections, ECU scans, maintenance resets, and code troubleshooting will find the X-OBD cable useful where SGW would otherwise block standard OBD2 access. It’s intended as a session-based solution to establish stable communication during service events.

• Retrieve and clear trouble codes, read live data streams, and perform system checks
• Speeds up diagnostic cycles by removing gateway-related communication failures
• Works as a data transfer interface — functionality depends on your scanner and software

Who is this for: The X-OBD FCA 12+8 SGW Bypass OBD2 Cable is aimed at professional automotive technicians, independent repair shops, and knowledgeable DIYers who work on FCA vehicles from 2018 onward and use professional scanners. If you need a non-destructive way to allow compatible diagnostic devices to access SGW-secured vehicle networks during inspections and repairs, this adapter provides a durable, reusable solution that preserves the factory harness and supports reliable data communication.
