Electrical system and method of operating an on-board network

The invention relates to a vehicle power supply (1) and a method for power transmission to the vehicle electrical system having circuit means (30, 30 ', 30' '), which are embedded in such a manner electrically at defined grid points in the pipe network (20) of the electrical system that lines (21, 22, 23) at least temporarily for the production of a particular vehicle electrical system or power transfer function to a wiring harness (LS) can be combined by being connected together so parallel and / or serially, that different lead configurations of each interconnected lines and so that different on-board network configurations are possible.
