    If none of the up//right/left actions work, but you can hear the pump motor running - and probably making lots of squealing - then the problem is most likely bad connections in the cable that has the solenoid signals. That's the connector with three pins on the MM1, not sure about the MM2. Basically the lack of solenoid signals is deadheading the pump and/or activating the left angle piston.

    NEH is correct as that wiring harness (plow side) will brake the wires just out of the molded plug. This is usually visible where it is broken.
