Mopar part number 68363277AA is a genuine OEM Engine Control Module (ECM) designed for 2019–2022 Ram trucks equipped with the 6.7L Cummins diesel engine. The ECM is the primary engine computer responsible for managing critical functions including fuel injection timing, turbocharger operation, emissions system control, and overall engine performance.

This OEM Mopar ECM is a direct replacement for the factory engine computer and is commonly used for ECM replacement, engine computer swaps, tuning applications, or repairing damaged modules. Because this module ships unprogrammed, it allows custom tuning or dealer programming to match the truck’s VIN and calibration.

Manufactured to Mopar factory specifications, the 68363277AA ECM ensures proper communication with the vehicle's sensors, transmission control systems, and onboard electronics to maintain reliable operation in demanding diesel truck applications.
