The invention relates to an intelligent current distribution system for vehicles and a method for manufacturing the system. In the system, the current is distributed to loads through intelligent connecting sockets (1). The sockets are mounted in desired locations on a cable (2), whose message communication bus (11) or a socket input-connector (7) is used to deliver control commands to control electronics (14-17) controlling operation of the socket. The control electronics include a basic program memory (16), in which are stored operating instruction programs for all necessary functions of several sockets in the system. Thus, any socket can be randomly located at least within a limited portion of the current distribution system. The socket is modified for individual operation during or after installation of the socket. Therefore, in the parameter program memory (17) there are stored parameter programs, which control individually the functions of a socket and which are predetermined specifically for each socket. The parameter programs control only a limited number of the function control programs of the basic program memory (16) to make only predetermined function control selections for said individual operation.
