Abstract: An apparatus for providing secure access to a trailer connector includes: a cover, a locking device, and a controller. The cover is configured to be secured to a trailer and to cover at least one connector of the trailer. The cover has an open position in which the connector(s) are accessible and a closed position in which the connector(s) are inaccessible. The locking device has a first state configured to hold the cover in the closed position and a second state configured to permit the cover to move from the closed position to the open position. The controller is configured to cause the locking device to change from the first state to the second state, to permit the cover to move from the closed position to the open position, based on an authorization.
