    I just inherited a 9 ft MM1 SEPH Fisher Plow. Can this style be converted to a 3 wire set up like the Insta Act Power Packs? I have no experience with this type of unit. Hoping that I can convert it.

    The difference between the 2 plug MM1 (sehp) style wiring and the 3 plug (mm2) style is that they split the control wires out of into it's own plug.
    The power plug is the same, just change the headlights over to the new style and pickup a 3 pin control harness for the plow side. easy swap... I'm doing the opposite for myself... adding the old 9 pin lights/control to a MM2 I picked up to replace it.
