    I got a good deal on a fisher ld 7.5 3 plug. Has anyone mounted one on a 2007-2015 gmc? I have a 2011 gmc 1500. Will mm2 pushplates work with this plow? What about a wiring harness? Any help would be appreciated, thank you.

    So do you have the truck side mount and wiring with it? Or just the plow alone?

    If you have truck side mount and wiring, see if you can get a couple of part numbers or post pictures.

    You didn't say if the plow itself is actually a MM1 or a MM2. The pushplates are compatible with either. If the plow is old enough to be a MM1 though, you will likely have problems with the A-Frame on the plow hitting the bumper on that truck.

    If the plow has the big yellow handle on the front of the tower that moves the pins in and out, it is a MM2. If it has the pins on the tower with the big handle on the side of each pin to pull them out manually, it is a MM1. 3 plug wiring could be either.

    The plow is a MM1, won't work with my truck. Thank you for the help.

    I know plenty of guys still running MM1 plows on newer trucks with no issues

    There is a fitment issue with 07-14 gmc, the drop leg hits the bumper.
