Engine installation harness for installing a Cummins ISX engine (CM2250 engine electronics) into a Kenworth truck with NAMUX2 chassis electronics.
NOTE: This harness is only compatible with a Kenworth NAMUX2 electronics chassis. NAMUX2 electronics are typically found on 2008-2010 year model Kenworth heavy duty class 8 trucks such as W900 T800 and T660. If you are uncertain of your exact chassis electronics please call for fitment confirmation.
Kenworth 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.
