This is a engine harness that will facilitate the installation of a EPA13 Paccar MX13 engine into a Peterbilt NAMUX3 truck that came from the factory with EPA10 chassis electronics.
Engine Harness emission breakout may or may not be direct fit depending on the connectors currently on the chassis side emission connectors. Peterbilt uses multiple chassis emission breakout connectors at the factory level.
NOTE: This harness is only compatible with a Peterbilt NAMUX3 electronics chassis. NAMUX3 electronics are typically found on 2011 and newer Peterbilt heavy duty class 8 trucks such as 367, 386, 388 and 389. If you are uncertain of your exact chassis electronics please call for fitment confirmation.
