    Adding 4H Switch (18-21)

    Just looked back into this thread. Good stuff Hilly. Does the middle knob work the rear diff locker?

    Adding 4H Switch (18-21)

    I have also installed the 4H Switch in my 2018 Max, Limited with HD trailer tow. Works great! But, also tried installing the upper shift selector switch that has the diff locker switch. Running into the dreaded "not being recognized by the TCCM issue". Does anyone know a way around this...
