The Baldwin's Performance CM849 In-Cab Harness is purpose-built for 2006–2007 5.9 Cummins third gen trucks running the CM849 ECM relocated inside the cab. If you are moving your ECM out of the engine bay for heat protection, cleanliness, or competition purposes, this is the harness built specifically for that application. 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 built to outlast OEM in every condition a working or competition diesel truck will face — under the hood heat, oil exposure, moisture, vibration, and time.

Designed for the 2006–2007 5.9 Cummins with the CM849 ECM relocated to the inside of the cab.
