This is a engine harness that will facilitate the installation of a EPA10 Paccar MX engine into a Peterbilt NAMUX4 truck that came from the factory with Paccar MX-13 chassis electronics.
Engine Harness emission breakout may or may not be direct fit depending on the connectors currently on the chassis side emission connectors. Kenworth uses multiple chassis emission breakout connectors at the factory level.
NOTE: This harness is only compatible with a Peterbilt NAMUX4 electronics chassis. NAMUX4 electronics are typically found on 2013 -2016 Peterbilt heavy duty class 8 trucks such as 567 or 579. If you are uncertain of your exact chassis electronics please call for fitment confirmation.
