Cabling arrangement intended for motorized vehicle and similar

A system for transmitting power and signals in a motorized vehicle, the system comprising:

• an electrical power supply;
• a plurality of different types of electrical components having multiplexing circuitry;
• and
• a first busbar electrically connected to the power supply and the electrical components, the busbar comprising at least two power conductors connected to the power supply and at least two signal conductors, the conductors comprising respective elongate strips of conductive material separated from each other by dielectric material and assembled into a layered structure,
• wherein the plurality of the electrical components are all connected to the signal conductors, wherein respective multiplexed control signals transmitted on the signal conductors can be received and used by specific ones of the electrical components, and wherein the plurality of electrical components are connected to the power supply by the power conductors.
