Abstract

An automotive electrical body system includes a plurality of electrical assemblies coupled to at least one automotive body component. Each of the assemblies includes a heating element for heating the at least one component, a motor for actuating the at least one component, or a switch configured to toggle the at least one component on and off. Each of the assemblies also includes a wireless communication module for receiving wireless signals, and, in response to the wireless signals, controlling operation of the heating element or motor. An electrical conductor interconnects each of the electrical assemblies and carries electrical power to each of the electrical assemblies.

Claims
