    My 2004 2500HD has this problem I think! When you turn down the dimmer switch for the interior lights the plow lights go off and the truck lights come on. Is this normal? My Boss plow was installed by the Boss Dealer.. just wondering if they did something wrong.

    No it's not normal...well, it is if it's wired wrong LOL.

    They have the power wire for the plow harness connected to the wrong power source in the under dash connector box..they must have connected it to the interior light circuit

    Here a diagram showing where you want to connect it... now theirs 2 pins circled in red in this diagram and you'll need to see which of the two is only powered in the "run" and "accessory" key position but one of them will be.
