Streamline your engine conversion with the Kustom Truck Engine Installation Harness, designed for installing a Cummins ISX engine with CM2250 electronics into Pre-NAMUX 2004-2005 Peterbilt trucks equipped with Cummins ISX CM870 chassis electronics. Engineered specifically for engine replacements, this harness facilitates seamless integration of the Cummins ISX engine with the analog electronics of Peterbilt class 8 trucks, including common models like 379, 378, and 357, ideal for mechanics and fleet owners performing engine swaps. The kit includes a precision-engineered harness with emission harness breakout connectors, which may require matching to your chassis connectors using the provided pinout sheet due to variations in Peterbilt’s factory chassis harness connectors.
