    Abstract: The invention provides a trailer diagnostics device. The device includes an input interface for connection to a wiring harness of a towing vehicle. The input interface is operable to measure an electrical signal (current flow) in one or more electrical wires of the wiring harness operably connected to a trailer. The device also includes an output interface for connection to the wiring harness. The output interface is operable to apply a test signal (test voltage) to the one or more electrical wires of the wiring harness operably connected to the trailer. The device further includes a processor which is connected to the input interface and the output interface. The processor is operable to determine the effect of the applied test signal (test voltage) on the measured electrical signal (current flow) and transmit a fault status of the one or more electrical wires to a user via an external communications interface.
