A wiring system for use in vehicles wherein a common single conductor bus is utilized for both power and control function transmission. A plurality of transmitters attached to the bus receive power from the bus and supply control signals to the bus as required. A plurality of receivers, attached to the bus, receive power and the control signals from the bus. Each receiver is tuned to respond only to the particular control signal produced by a single transmitter. Upon receipt of the appropriate control signals, the receivers couple power from the bus to various loads.
