Fish Tuning 2018-2024 6.7L Cummins Security Gateway Bypass Cable (FT2018-19-20BypassCummins)

Unlock full diagnostic and tuning access on your 2018–2024 Ram with 6.7L Cummins. This Fish Tuning Security Gateway Module (SGW) Bypass Cable is the essential permanent solution that restores unrestricted communication with the ECM.

Starting in 2018, Ram trucks added a Security Gateway Module that blocks most aftermarket tools from freely accessing the engine computer. This cable bypasses that module so you can flash tunes, adjust settings, and use diagnostic equipment without restriction.

Key Benefits & Uses

• Required to flash CSP5 tunes with EFILive on 2018+ trucks
• Enables EZ LYNK functions such as tire size calibration and aftermarket remote start
• Works with MM3 when the security module fails or for general SGW bypass
• Allows normal use of Snap-on and other OBD-II scanners
• Supports installation of accessories like AMP Research PowerSteps
• Once installed, your factory OBD-II port continues to function normally

Important Installation Notes

This cable is designed for permanent installation and is not intended to be removed and reused on another vehicle. Leave it installed for continuous bypass functionality (required for CSP5 switch use with EFILive).

Compatible with 2018–2024 Ram 2500/3500 trucks equipped with the 6.7L Cummins.
