    I am needing the wiring harness part numer and where to buy, for the 2014 GMC Sierra Denali 2500HD. I have the controller and V blade. Bought a new truck.

    Thanks Greg

    You may want the complete control kit not including a controller (MSC15102)
    And if your Denali is a late model, you may need the new headlight adapter (MSC09044) because GM changed wiring configurations slightly on the new 2500/3500's. Double check your headlight bulb configurations
