The Baldwin's Performance CM2100 Stock Harness is purpose-built for 2007.5–2009 6.7 Cummins third gen trucks running the CM2100 ECM in the factory stock location. Every harness is built with the highest quality materials available — a premium OEM-grade upgrade designed to outlast the factory harness in every measurable way.

Construction starts with all new OEM connectors and terminals paired with TXL automotive wire featuring chemically cross-linked polyethylene insulation engineered for high heat environments. The harness is flame resistant, moisture resistant, oil resistant, gasoline resistant, diesel resistant, grease resistant, and resistant to most solvents and acids.

From there every harness is fully wrapped in Tessa tape for an additional layer of protection against cuts, abrasions, and environmental hazards. Over that is a full loom of 10 mil PET semi-rigid split braided loom for structural protection and a clean professional appearance. Finally each harness is finished with dual wall heat shrink at all termination points to lock out moisture and ensure long-term reliability.

The result is a harness that is built to outlast OEM in every condition a working diesel truck will face — under the hood heat, oil exposure, moisture, vibration, and time.

Designed for the 2007.5–2009 6.7 Cummins with the CM2100 ECM remaining in the stock location. For in-cab ECM relocation see the CM2100 In-Cab Stock Harness.
