Autel OBD2 Security Gateway Bypass Cable for 2018–2020 Ram 1500/2500 Cummins — 16Pin+2Pin Plug-and-Play Access to Modules

The Autel Original OBD2 Adapter Security Gateway Connector (16Pin+2Pin) is a plug-and-play bypass cable that lets compatible diagnostic scanners access most vehicle modules on 2018–2020 Dodge Cummins RAM 1500/2500 models by routing around the factory security gateway.

This cable provides a direct physical path between your scanner and the truck’s control modules so you can read live data, pull diagnostic trouble codes, and perform routine maintenance checks without modifying the vehicle. It is an adapter only—not a diagnostic tool—and is built specifically for Cummins diesel Ram models from 2018 through 2020 (not compatible with EcoDiesel or some “Classic” variants). Confirm your truck’s model year, engine type, and scanner compatibility before purchase.

Will this cable work with my 2018–2020 Dodge RAM?

This cable was engineered for 2018–2020 Dodge Cummins RAM 1500 and 2500 pickup trucks with the Cummins diesel engine. Some variations in engine control modules and onboard protocols can still prevent a successful connection, so verification is essential.

• Compatible: 2018–2020 RAM 1500/2500 with Cummins diesel (not EcoDiesel).
• Not compatible: 2020 Bighorn variant and certain 2018 "Classic" models.
• Check your truck’s OBD connector and engine type against product photos before buying.

How do I install and use the Autel SGW bypass cable?

Installation is simple and non-permanent: the cable connects between the factory OBD port, the truck’s green security module, and your scanner. No soldering or module replacement is required; it’s designed for quick hookup and reliable signal transfer during diagnostic sessions.

• Step 1: Plug the 16-pin male into the vehicle’s factory OBD port under the dash.
• Step 2: Insert the small 2-pin bypass connector into the truck’s green security module.
• Step 3: Attach your OBD2 scanner to the 16-pin female connector to access data.

What diagnostic functions can I expect when using this bypass cable?

By creating a direct communication route, the cable enables your compatible scanner to access most control modules (except the radio) for reading live parameters and retrieving or clearing fault codes. Exact capabilities depend on the scanner’s features and vehicle protocol support—not the cable itself.

• Enables live data streaming from vehicle modules for troubleshooting.
• Allows retrieval and clearing of diagnostic trouble codes if scanner supports it.
• Works with body and engine modules such as BCM and RFH but excludes stereo access.
