Just came across this video showing a fusible link that gives you a button in the cab on snow plow packages to ideally control a snowplow. I did a quick search online and wasn't able to find much, has anyone come across this button? Seems like the guy here is thinking about using this as an upfitter switch of sorts (to power a winch), but the purpose of the button seems like it reduces use on other electrical systems on the truck to enable something with more load (as seen in this thread)

Here's the video, button is shown around the 8:00 mark

 

That's not a fusible link, its a button that tells the BCM to disconnect/turn off 4 items to lessen the load on the electrical system and turns on the plow circuit pigtail for the plow controller. I don't know where he is going to get 100 amps out of that button, wish him luck. In these very threads, there is a thread on the snow plow feature and how to add it.
