Electrical system for a vehicle that provides power and communications to vehicular devices includes a (singular) electrical bus having elongate wires, and connector assemblies situated at different locations along the wires. The connector assemblies include a splice housing defining an inlet and outlet for the wires, the wires passing from the inlet to the outlet through the splice housing without being interrupted, and a connector attached to the splice housing. An electrical conduit, such as one or more wires, is attached at one end region to each connector and at an opposite end region to a respective cluster or cluster control unit. Each cluster or cluster control unit is electrically coupled to at least one vehicular device. Power and communications are provided to the vehicular devices by a power source and communications source through the bus.
