Simplify your engine swap with the Kustom Truck Engine Installation Harness, a direct-fit solution for installing a Detroit Series 60 engine (DDEC5 electronics) into a Peterbilt 387 or 587 truck with NAMUX2 Cummins CM2250 chassis electronics. This harness enables seamless integration, ensuring a fully functioning dash with all switches and gauges operating as if the Detroit engine were factory-installed. Designed for mechanics and fleet owners upgrading Peterbilt 387 or 587 heavy-duty class 8 trucks, typically from 2011-2012, this harness supports custom builds and fleet conversions by interfacing the Detroit Series 60 engine with the truck’s NAMUX2 and Cummins CM2250 chassis electronics. Note: Even with the harness fully installed, the truck’s dash may not function without ECM/cab programming. This harness is only compatible with Cummins-based Peterbilt 387 or 587 NAMUX2 chassis electronics; NAMUX2 electronics are typically found on 2011-2012 models. If uncertain of your exact chassis electronics, contact Kustom Truck for fitment confirmation. Upgrade your Peterbilt truck’s engine system with Kustom Truck Parts’ precision-engineered harness, trusted for quality and reliability.
