The Ford's built in brake controller tells me when a trailer is connected, or disconnected. I *think* it uses the brake line for this, and, if so, should tell me if if no brakes are connected.
But anyway, we'll be testing the brake line the same way and at the same time we check the brake lights: by pressing the brake pedal. If the lights don't light or there's not 7A or so on the trailer brake line, then there's trouble.
