Trailer brake controller wire harness
When connecting my brake controller to the wire harness supplied with the 2022 F53 chassis there's a brown/blue wire labeled BOO Signal. It would seem its the stop wire since that's the last wire left from the controller. When I press the brake I don't get any trailer braking. When I use the manual button on the controller the brakes work. That makes me question what does BOO Signal mean? Have I wired it wrong?
