Product details
Cummins B-Series ECM Wiring Harness
What Is This Part?
The Cummins 5271318 is an ECM wiring harness (CM2350, B-Series) for Cummins B-Series engines. Application: Cummins B-Series engines with CM2350 ECM (confirm connector set).
The harness links the CM2350 engine control module to the engine sensors and actuators. A chafed, burnt or corroded harness causes intermittent sensor codes, derates and no-start conditions that are often mistaken for an ECM failure.
