CM2250

Corroded, melted, or mechanically damaged ECM connectors on Cummins ISX15 engines with CM2250 electronics are a common source of intermittent fault codes, sensor communication failures, and derate conditions. These issues often trace back to a single connector rather than the entire harness assembly.

Kustom Truck Parts offers CM2250 Cummins engine harness repair kits that target the specific connector at fault. Each Cummins connector repair kit includes genuine OEM plugs, pre-crimped 18" GXL copper wires, J1939 CAN bus cable, J1587 twisted pair datalink, and cavity plugs for unused positions. Kits are available for the E60-Pin ECM Connector for the engine-to-cab harness for the exact failure point.

Designed for Freightliner, Western Star, Peterbilt, and Kenworth chassis in both OEM maintenance and conversion applications, these kits eliminate the need for a full harness replacement. Browse below by connector type, or contact our team for serial number verification.
