Optimize your truck’s electrical system with the Kustom Truck Ground System Harness, designed for Kenworth NAMUX2, NAMUX3, or NAMUX4 chassis electronics, as well as Peterbilt NAMUX4 chassis electronics, to effectively ground the cab, engine block, frame, and alternator back to the battery negative. This harness is commonly used during engine conversions where the alternator shifts from the driver’s side to the passenger’s side, such as Paccar engine replacements, or when performing a cab swap with a newer NAMUX2, NAMUX3, or NAMUX4 cab onto an older Kenworth or Peterbilt frame/chassis. Tailored for heavy-duty class 8 trucks, including Kenworth models like W900, T800, T660, T680, and T880, and Peterbilt models like 567 and 579, this harness ensures reliable electrical connectivity for optimal performance. The kit includes a precision-engineered harness for secure grounding across critical components. Note: NAMUX2 electronics are typically found on 2008-2010 models, NAMUX3 on 2011 and newer models, and NAMUX4 on 2016 and newer select Kenworth and Peterbilt models . If uncertain of your chassis electronics, contact Kustom Truck for fitment confirmation. Ideal for engine conversions or cab swaps, this harness delivers consistent and dependable performance.
