    I bought a 2000 Ford with a MM SEHP (2 plug) harness wired in already.
    I finally found a plow but it has three plugs. What do I need to do to
    hook up this (3 plug) plow to my (2 plug) harness?

    If that is the 2 plug setup that has the relays in it, heres an option for ya. You could take that off your truck and sell it to me, then contact the guy named Doakster on here and buy the 3 plug setup he has sittin around from his old plow, he bought a new V and got new wiring.

    Im looking for a 2 plug with relays setup for a Fisher MM1 plow for a friend of mine, and if you have one and want to do this deal, let me know.

    All you need is a 9 pin harness 8246 and a 2 pin power harness 21294 aka 8245. It's easy to swap over. Instructions come in the bag for the 9 pin harness. The plow your looking at is a SEHP right? You can also go to Fisher's website and E Search part numbers to see schematics and diagrams. Good luck
