X-OBD FCA 12+8 SGW Bypass OBD2 Cable (2018+) — Plug-and-Play, No Cutting

The X-OBD FCA 12+8 SGW bypass OBD2 cable lets compatible diagnostic tools communicate with 2018+ Chrysler, Dodge, Jeep and Fiat vehicles that use the factory Security Gateway (SGW) connector.

This purpose-built adapter provides a plug-and-play link between an OBD2 scanner and FCA vehicles fitted with the 12+8-pin SGW harness. Designed to avoid cutting or modifying factory wiring, the cable makes it practical for technicians and knowledgeable owners to run maintenance diagnostics, read ECU data, and perform routine checks using supported diagnostic hardware and software.

How does the cable bypass the SGW and connect my scan tool?

The X-OBD cable reroutes the vehicle’s SGW 12+8-pin connector into a standard OBD2 interface that compatible scanners can use. It creates a direct, stable electrical connection so diagnostic devices can exchange data with vehicle ECUs without altering the factory harness.

• Fits the OEM 12+8-pin SGW connector on supported FCA vehicles.
• Outputs a standard OBD2 plug compatible with many professional scanners.
• No cutting or splicing — installs by plugging into existing ports.
• High-purity copper wiring and reinforced connectors for signal integrity.

Which vehicles and diagnostic tools are compatible?

The adaptor is intended for FCA models from roughly 2018 onward that use the 12+8 SGW connector, including many Jeep, Dodge, Chrysler and Fiat cars and SUVs. It is not a standalone scanner; you must use it with an external OBD2 device or diagnostic software that supports your vehicle systems.

• Works with Jeep Renegade, Compass, Cherokee, Wrangler, Grand Cherokee models and similar vehicles.
• Supports Dodge Ram, Durango, Journey, Charger, Challenger families and Chrysler Pacifica, 300 models.
• Compatible with many Autel series scanners and other professional OBD2 tools listed by vendors.
• Functions as an interface—scanner firmware and software still required for full operations.

Is installation difficult and will it damage factory wiring?

Installation is intended to be straightforward and non-destructive: the adapter plugs into the factory SGW connector and the scanner plugs into the adapter’s OBD2 end. Because it avoids vehicle harness modifications, it preserves factory wiring and can be removed without leaving permanent changes.

• Plug-and-play setup — no vehicle wiring cuts or soldering necessary.
• Durable connectors reduce wear from repeated use.
• Designed for both shop technicians and experienced DIYers.
• Maintain OEM wiring integrity for warranty-friendly diagnostics.

What communication and performance can I expect during diagnostics?

When paired with compatible scanners and proper software, the cable supports reliable ECU communication for routine inspection and maintenance tasks. It acts as a stable data path so the diagnostic device can read codes, monitor live parameters, and complete supported service functions more efficiently.

• Stable signal transmission using solid copper internal wiring.
• Reduces connection errors common with improvised adapters.
• Works without requiring continuous Wi‑Fi, subscriptions, or gateway updates to start communications.
• Depends on the scanner/software capability for advanced functions.

Who is this for: The X-OBD FCA 12+8 SGW bypass cable is aimed at independent mechanics, repair shops, fleet technicians and informed vehicle owners who need a reliable, non-destructive way to run diagnostics on 2018+ FCA vehicles with the 12+8 SGW connector. It fits workflows that already include a compatible OBD2 scanner or professional diagnostic platform and prefer a one-time, hardware-based gateway solution to access vehicle data.
