1.Remove the two gray pin retainers from the back of the connector.
2.Locate the back of the OBD2 connector and replace the cables at pins 6 and 14: change the blue wire of the bypass cable to the yellow wire at the pin, and replace the brown wire of the bypass cable with the brownish wire at the pin. For the 2019-2024 models, replace the blue wire of the bypass cable with the brownish wire of the pin, and the brown wire of the bypass cable with the yellow wire of the pin.

DESCRIPTION

Product Overview

Starting with many 2018+ Ram 6.7L Cummins trucks, FCA introduced a SGW that limits certain aftermarket communication, programming, and configuration functions through the factory OBD2 port. These restrictions can prevent some tuning and diagnostic tools from accessing advanced vehicle functions.
The Bypass Cable provides an alternate communication path through the vehicle CAN network, bypassing SGW communication restrictions and allowing compatible aftermarket tools to communicate with supported vehicle modules.
It restores access for supported tuning, diagnostics, and configuration functions while keeping the factory OBD2 system available for normal vehicle operation and everyday use.

Key Features

Durable Automotive Construction: Built with high-temperature wire sleeving and vibration-resistant materials for reliable long-term performance.
Maintains OEM Functionality: Keeps the factory OBD2 port available for diagnostics, code scanning, inspections where applicable, and supported tuning features.
Enables Supported Tuning Access: Bypasses factory Security Gateway Module restrictions, allowing compatible tuning platforms such as EFILive, EZ LYNK, and MM3 to communicate with supported vehicle modules.
Supports Vehicle Configuration Changes: Works with compatible tools like AlfaOBD and JScan for supported functions including tire size adjustment, gear ratio updates, remote start configuration, and accessory programming.

FAQ

Q: What does a Cummins SGW bypass cable do?

A: The SGW bypass cable bypasses factory Security Gateway Module communication restrictions, allowing compatible tuning and diagnostic tools to communicate with supported vehicle modules.

Q: Does this cable add horsepower or improve performance?

A: No. The bypass cable does not increase power or modify ECM calibration. It only restores communication access for compatible tuning and diagnostic tools.

Q: Why do 2018+ Ram Cummins trucks need an SGW bypass?

A: The factory Security Gateway Module limits certain aftermarket communication functions through the OBD2 port. A bypass cable allows supported tools to access advanced diagnostics, programming, and configuration features.

Q: Can I leave the bypass cable installed permanently?

A: Yes. It can be installed behind the dash and left connected for regular use, or removed and reused when needed.

Q: Is this required for EFILive, EZ LYNK, or MM3 tuning?

A: Many aftermarket tuning tools require SGW access to perform certain functions on 2018+ Ram trucks. Compatibility depends on the specific tool and vehicle configuration.
