Engine installation harness for installing a Cummins ISX engine (CM2350 engine electronics) into a 2011 - 2016 Peterbilt truck with NAMUX3 chassis electronics.
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 389, 388, and 367. If you are uncertain of your exact chassis electronics please call for fitment confirmation.
Peterbilt uses many variations of chassis emission harness connectors on the factory chassis harness. With that said, the emission harness breakout connectors on this engine harness may or may not match directly to the connectors on the chassis. However, the harness will include a pinout sheet for the emission connector breakouts that provides the required information for you to match up to any existing or additional chassis emission connections required.
