    I am looking at picking up a used mm1 that is an old 2 plug style. What would you have to do to convert it to a newer 3 plug style?

    im pretty sure you would have to buy a whole new pump (insta-act), make mounting brackets for the pump to mount onto the plow frame, and switch out the lights

    If the truck side of the wiring is a three plug isolation setup then it is easy. Get a new set of lights with the plowside light harness AND a plowside control harness.

    If you need all the truck side stuff it gets more expensive but not really much more complicated, just follow the directions.

    I don't have my parts book in front of me but any dealer should have the lights and anything else you need in stock.
