I have a 2019 Silverado 2500 HD with the 6 L gas engine. I also have a winch that mounts into my receiver hitch. I will normally use a separate battery for my winch, but I would like to have the option to hook the winch to the truck's battery. Because of the configuration of the battery, I would like to use that hexagonal terminal that sticks up from the battery, apparently for jump-starting. Does anyone make a clamp that would make a good connection to this post?
