Enhance your Kenworth truck’s transmission integration with the Kustom Truck Eaton Fuller Manual Transmission Sensor Harness, a direct-fit solution for Kenworth trucks with NAMUX2 (2008-2010) or NAMUX3 (2011+ W900, T800, T660) chassis electronics. This harness is essential for two common applications: replacing a Paccar engine, which uses ABS-based vehicle speed, with a Caterpillar, Cummins, or Detroit engine requiring a manual sensor, or converting from an automated transmission, where the TCM relays sensor signals, to a manual transmission. In both cases, the harness provides the electronic interface for vehicle speed, transmission temperature, and reverse switch functions, ensuring seamless dash and gauge operation as if factory-installed. The kit includes the sensor harness only; sensors are not included. Ideal for mechanics and fleet owners performing engine or transmission swaps on Kenworth W900, T800, or T660 models, this harness supports custom builds and fleet upgrades. Note: This harness is only compatible with Kenworth NAMUX2 or NAMUX3 electronics chassis; NAMUX2 is typically found on 2008-2010 models, NAMUX3 on 2011 and newer heavy-duty class 8 trucks (e.g., W900, T800, T660). If uncertain of your chassis electronics, contact Kustom Truck for fitment confirmation. Upgrade your Kenworth truck’s transmission system with Kustom Truck Parts’ precision-engineered sensor harness, trusted for quality and reliability.
