Simplify your engine conversion with the Kustom Truck Engine Installation Harness, custom-designed for installing a Cummins ISX engine with CM870 electronics into a Pre-NAMUX 2004-2005 Kenworth truck equipped with Caterpillar-based chassis electronics. Engineered for seamless integration, this harness ensures reliable connectivity between the Cummins ISX CM870 engine and the analog Caterpillar electronics of Kenworth class 8 trucks, such as models W900, T800, or T600, delivering robust performance in heavy-duty applications. The kit includes a precision-engineered harness tailored for precise fitment, making it ideal for mechanics and fleet owners performing engine swaps or replacements. Note: This harness is exclusively compatible with Caterpillar-based Kenworth Pre-NAMUX (analog) electronics chassis, typically found in 2004-2005 models. Due to variations in factory chassis emission harness connectors, the emission breakout connectors on this harness may require modification for direct fitment. To ensure proper fitment, provide the last 6 digits of your chassis VIN and the Cummins engine serial number when ordering, and contact Kustom Truck for fitment confirmation if uncertain about your chassis electronics. Upgrade your Kenworth truck’s engine installation with this precision-engineered harness, crafted for durability and performance.
