    Where are you pulling 12V KO hot for plows on these trucks?

    In the older trucks you normally needed (should) grab the ACC or ON wire coming off the key tumbler before the BCM, and add a relay. Some of the newer trucks have a few blunt cut wires that supply power...

    This is a good idea depending on load. I hardwired a GPS into my car this way.

    2013 3500hd here, to get a keyed circut i used a fuse tap in the under hood fuse box. All the keyed circuts are in the under hood box now. Im not sure if that 2010 wire buliten above applies to your 2015. If it does that sounds like an easier route. Maybe! Lol....

    On my 2010 Sierra, there is an underdash connector in the M-BEC for use with aftermarket accessories. X14 pin 7 is 12V, 10 amp with key on. The fuse that protects this is located in the underhood fuse panel, I can get the fuse location if you need. You do need GM connector 20791502 to mate to it, which comes with a wire in position 8 that I removed and spliced into my plow feed wire.
