Simplify your engine conversion with the Kustom Truck Engine Installation Harness, custom-designed for installing a Cummins ISX engine with CM2350 or CM2450 engine electronics into a Peterbilt 387 truck equipped with NAMUX1 chassis electronics and Cummins ISX CM870 engine electronics. This harness ensures seamless communication between the Cummins engine and the CM870-based NAMUX1 chassis electronics, delivering reliable performance in heavy-duty class 8 trucks. Engineered to accommodate Peterbilt’s varied chassis emission harness connectors, the kit includes a detailed pinout sheet for the emission connector breakouts, providing the necessary information to match or adapt to existing or additional chassis emission connections. Ideal for mechanics and fleet owners performing engine conversions or upgrades, this harness offers durable construction and precise fitment for 2006–2007 Peterbilt 387 models. Note: This harness is only compatible with Peterbilt 387 trucks featuring Cummins-based NAMUX1 chassis electronics, typically found on 2006–2007 models. The emission harness breakout may not be a direct fit due to multiple factory-level chassis emission breakout connectors. To ensure proper fitment, provide the last 6 digits of your chassis VIN and the Cummins ISX engine serial number when ordering, and contact Kustom Truck for fitment confirmation if uncertain about your chassis electronics. Enhance your Peterbilt 387’s engine installation with this precision-engineered harness, crafted for durability and precision.
