I think I would look into whats available in snow removal equipment. Most are high draw currents, but I think you will be looking at at least 2 connections, maybe 3, and they are probably ugly as well. The chassis end of the plug(s) can be hidden in a box on the chassis, but the clip ends are going to be hanging out where they can be seen. Can the plugs be concealed so they are only visible when the clip is off? That may not be so bad. Gene
