A brake-control module for a first trailer of a tractor-trailer combination reduces braking response time for the second trailer and subsequent trailers in the vehicle train. The addressable tap includes an input port for receiving an input signal and output ports for providing outgoing signals to receiving equipment and a controller for providing addressable per port switching. In one embodiment, the invention provides power factor correction to the system by measuring power factor to determine whether it is within predetermined limits and introducing a delay into the timing of the phase triggers if it is not. Relevant profiles can be determined based on the export mechanism, destination or type of content.
