Abstract
A cable system for a truck trailer for reducing the number and/or size of wiring in a commercial trailer cable system from seven to four, three, or two, while also facilitating bidirectional communication with all connected electronic devices in the trailer. The cable system has a ground cable, a power cable, and zero, one or two additional communication cables that may carry analog and/or digital communications between the control circuit and components of the trailer such as turn signal lamps, brake lamps, backup cameras, environmental sensors, and the like. A transformer for increasing the voltage on the power cable is disclosed, allowing the power and ground cables to be smaller without reducing power delivered to the trailer.
