Lowbeams dont work when plow disconnected

    Hey guys,

    So I got a Boss V-plow installed on my 2008 F-350 this past winter. Everything works great with the lights when the plow is hooked up, but when its unhooked from the truck, my trucks lowbeams do not come on anymore (yet they WILL come on when the plow is mounted up in I flip the switch to truck mode). The highbeams will come on no problem, but not the lowbeams. This only seems to happen when the plow is disconnected. I checked all fuses etc and they are fine.

    Any ideas?

    Try looking at the Boss web site. It should have a trouble shooting section on the site some where.
