    Ok, I am not new to plowing, but am new to plowing with my own truck. It is fully wired with a three wire kit and has the ears on it. I am looking to pick up a used plow. I understand there is MM1 and MM2. Although I am not sure what the differences are between the two. Also, at what point did it change from 2 wire to 3 wire on the plow side? Is there an easy adapter to convert a 2 to a 3 or am I better off just finding a 3 wire plow? Not plowing anything major, just my driveway and short private road leading to my driveway. Any suggestions or advice would be greatly appreciated. Thanks!

    If it has a 3 wire setup and minute mount push plates, both the MM1 and MM2 will work, as long as the plow side wiring is also a 3 plug setup. The MM2 is easier to mount and has a different style A-frame and headgear than the MM1. The wiring changed from 2 plug to 3 when fisher started using the Insta-Act pump, which was first used on MM1's. A 2 plug SEHP MM1 setup can be converted to 3 plug, It requires some rewiring and a new set of headlights. Obviously it would be easier to just find a 3 plug plow, but it depends on how much money you are looking to spend. Hope this helps - Nick
