The Cummins Engine Wiring Harness is a genuine Cummins harness for EPA17 15-liter ISX and QSX engines, carrying power and signals between the engine's sensors, actuators, and control module. It's wired for the 2017-emissions version of the 15-liter rather than an earlier ISX layout. On the QSX side, the Cummins 4393920 covers QSX15 engines built from 2018 through 2022. It comes new rather than remanufactured, so you replace chafed or heat-damaged wiring with a fresh harness.
