2018796 - HOPKINS BREAKAWAY KIT
Hopkins Engager System. These are for our new harness's to plug right in but you can just clip the end off to make it work with older trailers. This Kit comes with battery, battery box, breakaway switch & Pin/Cable. Also comes with instructions. Every electric brake trailer needs to have a working one of these on it. The dump trailers and real trailers use the on board battery in place of this.
