What are the build quality and durability features?

The ALTBET cable is made from sturdy materials intended to tolerate repeated use in shop and field environments. Reinforced connectors and strain relief reduce the chance of wear at common failure points, and the cable body resists kinking and abrasion for longer life.

• Heavy-duty connector housings for frequent plugging cycles
• Strain relief to protect termination points from damage
• Flexible, abrasion-resistant jacket for shop and roadside use

Will this cable work with my scan tool, tuner, or programmer?

The bypass cable is designed as a neutral interface between your vehicle’s OBD2 port and any standard OBD2-compliant diagnostic or tuning device. It does not modify communication protocols; compatibility depends on the tool rather than the cable. Confirm that your tool supports diagnostics or tuning for 2018–2020 Dodge Cummins RAM models.

• Works as a passive adapter between vehicle and tool
• Supports OBD2-standard connections used by most scanners and tuners

How should I install and store the cable to avoid issues?

Installation is straightforward: connect the cable to the vehicle OBD2 port and plug your diagnostic device into the cable’s opposite end. When finished, disconnect both ends and store the cable coiled in a dry place to prevent kinks or moisture exposure. Avoid sharp bends and keep away from heat sources.

• Plug into the vehicle OBD2 port, then attach your tool
• Disconnect both ends after use and coil gently for storage
• Store in a dry, temperature-stable place to prolong service life
