I have a 2021 Trailboss. While trailering an enclosed trailer, I am getting an auditory alert with a repetitive warning notice of “Check Trailer wiring” , and “Brakes are connected” All running lights are operating and functional. Its the annoying sound of the alert and the visual notice that keep showing up. Any suggestions?
Is the problem with the trailer pigtail, or the truck’s 7 pin plug?
