    hey guys,

    i went to hook my plow up the other day(mm1, 3 plug setup, old style lights) and got nada. Hooked up to my spare plow(exactly the same as my broken plow) and every thing works normally. When i hook to my broken plow, i dont get the red light on my control pad or any movement(i forgot to check if the lights work). I was playing with my good plow and the only harness that that stops all movement of the plow is the one that runs up to the headlight.

    Should i assume that this one is bad?

    Any opinions would be great.

    Possible options are

    a bad plug, or more specifically an individual pin in one of the connectors.

    a broken wire inside one of the harnesses wrapped in nylon.
