NAMUX3 Harnesses

Kustom Truck Parts provides advanced NAMUX3 harnesses for 2011–present trucks, covering Peterbilt (365, 367, 384, 386, 388, 389) and Kenworth (T660, T800, W900) chassis. With Chassis Node and CECU integration for enhanced J1939 functionality (support 250K baud rate chassis systems), these harnesses support Caterpillar, Cummins and Detroit Diesel engines. Engineered for engine swaps and OEM replacement, they ensure precise, plug-and-play connectivity across cab, chassis, and engine systems. Built for reliability in professional retrofits, our NAMUX3 harnesses help builders and installers to interface a new engine in an existing chassis in an efficient and timely manner.
