Abstract: A connector arrangement of a control system with a controller in a motor vehicle is designed so that it can be manufactured advantageously and is reliable in operation.To do so, the connector arrangement and the respective controller are designed so that several separate connector sockets with externally accessible contact elements are arranged on the controller, which is mounted on the vehicle's internal combustion engine as a surface-mounted controller, some of the contact elements being designed as high-current contact elements which are connected directly to one another through busbars running inside the controller.The respective mating connectors can be connected to the connector sockets, the mating connectors being electrically connected to components of the vehicle over cable harnesses or cable segments, where a first mating connector connected to cable segments is composed of partial mating connectors which can be handled independently of one another.

Abstract: The disconnection protecting device (12) for an electrical connector prevents or makes difficult manipulation of the electrical connector (11) to by-pass an automatic stopping device of a motor vehicle. The disconnection protecting device (12) includes a lock member (32) which can at least indirectly lock the assembled electrical connector (11) preventing its disassembly. The lock member (32) can be a retaining member (18) at least partially covering the electrical connector (11) or a locking element (33) inserted directly in the electrical connector (11) in the form of a plug lock or clip lock.
