    According to some websites when they upgraded to the plus they changed the fuel system and ecm to more "sophisticated" system. Which would mean I think you would need the wiring and even from the plus.

    From what I'm reading and comprehending it should be fine,

    The engines didn't change, just the Celect Plus has J1939 capability vs. yours that doesn't.

    It'll work just fine. May or may not use all of the sensors. If not and it throws a code just reflash according to the new cpl
