RAM 2500 and 3500 Cummins trucks built with the CM2450 ECU use a different switch fitment than earlier CM2350 platforms, which is why HP Tuners offers the H-M04-02 as a dedicated 6-position diesel switch for this ECU. Like other switches in the lineup, it allows quick selection between a stock calibration and up to five custom maps through a single rotary knob.

HP Tuners H-M04-02 Installation Notes:

• Matches the OEM CM2450 ECU used in 2013-2024 RAM 2500 and 3500 Cummins trucks.
• Switches between a stock calibration and up to five custom maps via a 6-position rotary knob.
• Ships with a 5 ft. OBDII pass-through cable for connection inside the cabin.
• Can be paired with an optional OBDII port bracket and HP Tuners Switch on-the-Fly, both sold separately, for added mounting flexibility.
