    hey all, i was wondering what i need part wise to convert an old MM1 2 plug system to the 3 wire fisher system. my truck is set up for a 3 wire, and im a mechanic at a fisher dealer, so i would imagine, all i need is the 3 plug harness for the lights, as well as a harness that would run to the solenoids, like my mm2 3 plug system, but does it use the same harness as my mm2? because the motor power harness is the same, i havent been into those old 2 plug systems much, only seen a handful come into the shop, mainly for hydraulic lift cylinder leaks, if someone has done this, shoot me the part numbers if you have them on hand. thanks.

    Not to be cruel, but if your a mechanic at a fisher dealer you should know and be able to get all that info easily.

    None of the guys at work could tell you or you couldn't look it up?That would be like working at Home Depot and asking about duct tape.:laughing:

    You will need the controle harness and light harness. Power is the same
