    Do any of you know where I can find the instructions and part #'s to convert a MM l plow with two plug set up to the current three plug set up? The truck was wired new this year with a current three plug set up.

    Thanks
    Ed

    You pretty much need to buy everything that a 3 plug involves. Ebay has a bunch of wiring on there now.

    I was told by a dealer that there is a harness that you need to convert add another headlight harness on the plow side.

    I just ordered everything he said I needed, I'll let you know how I make out.

    You can add intensifires to your MM1 under the Two plug style. Part 28800 ($232.00) obviously, thats your headlights. Then you need the brackets 28330 ($86.00) so you can mount the lights to the older headgears, then you need electric adapter kit 29033 for the wiring ($45.00).

    Ok guys. Im still not sure If I have a mm1 or 2. It said mm1 but from what I have seen it looks like a mm2.


    I will take pics so maybe someone here can tell me what I have going on. Its a latter model ezv. So is there two models of the mm1? Also my fish-stick is either V or Scoop. Cant control each wing individually. Does that help out?

    Ed, Lets put it this way, when your removing the plow from the truck, do you pull one lever on the front of the plow to disengage the attachment pins an lower the kick stand all at once?

    Or do you have to pull the pins on both sides of the truck yourself as well as lower the kick stand? If it is a one lever action, you have a mm2, if not......MM1.

    After you figure out which MM you have, you need to figure out which Pump you have.

    This is a photo of the Insta Act.

    These are general pictures, they do vary a bit, but are the same style either way. Also, Truckside, how many pins on each harness?

    Thanks for explanation.


    I have the mm2.

    And the insta act

    hm maybe I have 3 wire plug. I should go look.


    Does the new fish-stick for extreme V backwards compatible for the ezv


    seems like a nice feature to control each blade individually

    Alright......you've lost me! Do you know if you have 3 harnesses on your plow or not? Also, from what you are saying here, You can put your plow in "scoop" mode, you can angle it to a straight blade, but you can't angle either side back to the "V" position, or is it you can't angle the blade full left, or right?

    I keep forgetting to look. I can scoop V angle left and right.


    But I see the new version of the controller can control each blade separate. So you can make left blade scoop and right blade 90' angle. Sort of an L shape I guess. Im use to bobcats with protechs. So this is kind of new to me.

    Ok......If I am thinking about the same two controllers, yes you can simply plug the new style in and get the movements you want. Do you have a box style controller, or a hand held controller? If it's a hand held You can actually buy just the key pad, and switch plate controls and swap them into your actual controller.

    You should post some pics of both control and plow.
