Baldwin's CM2100 Motorsport Standalone Harness | Mil-Spec | Raychem DR-25 | In-Cab ECM | 6.7 Swap

The Baldwin's Performance CM2100 Motorsport Standalone Harness is the pinnacle of the CM2100 harness lineup — built in-house with military-specification components and aerospace-grade wiring materials for the ultimate in cleanliness, reliability, and serviceability. Built for 2007.5–2009 6.7 Cummins builds running the CM2100 ECM in a standalone configuration with the ECM relocated inside the cab, this is the harness for builders who refuse to compromise on any level. A standalone harness eliminates all factory body, chassis, and accessory wiring not required to run the engine — giving you a clean, purpose-built starting point for a swap build, competition truck, or any dedicated performance application. Moving the ECM inside the cab removes it from the harsh under-hood environment entirely, protecting it from heat, oil, vibration, and moisture that degrade ECM performance over time. Where the standard Baldwin's harnesses use TXL automotive wire, the Motorsport harness steps up to Raychem DR-25 and Tefzel wire — the gold standard in aerospace and motorsport wiring. Raychem DR-25 is a dual-wall heat shrinkable sleeving system used in military and aerospace applications, chosen for its outstanding resistance to heat, abrasion, chemicals, and solvents, along with excellent electrical characteristics, flexibility, and ease of installation. Tefzel wire is a fluoropolymer-insulated wire used in the most demanding motorsport and aerospace environments where standard automotive wire simply is not enough. Mil-Spec bulkheads provide the clean sealed connection point between the engine bay and the in-cab ECM location. Service loops and strain relief are built into the harness at every critical point for long-term reliability and easy serviceability. The result is the most capable CM2100 harness Baldwin's builds — standalone wiring with Mil-Spec construction and in-cab ECM relocation for the cleanest, most reliable, most serviceable competition build possible. This is the standalone configuration with in-cab ECM relocation. Factory body, chassis, and accessory systems are not retained.
