If the Hopkins Agility Brake Controller, part # HM47294 is installed and wired properly, the screen will display one red dot in the bottom right hand corner when a trailer is connected. The screen will be blank when no trailer is connected. Check the Operating/Setting Your Controller section of the instructions for the brake controller. It has a list of information the display on the brake controller provides.
In case you do not have the instructions, I have linked to them below.
