Abstract: A wiring harness for use in a networked wiring system wherein one or more multiplexed electronic circuits are contained within the wiring harness. Provision of such electronics within the wiring harness reduces the number of wires used in a networked wiring system without requiring their provision within sensor or actuator devices, or in external electronic boxes. Inclusion of such electronics within the wiring harness also eliminates the need for extra interconnections, and provides protection of the electronics from environmental conditions.
