The majority of connections in electric network of the car is executed by multicontact sockets in the plastic case. Sections (half) of sockets after connection usually are kept by the clamps cast in the socket case.
Sections of the big sockets, for example, installed under the dashboard connect together the screw passing through the center of the socket.
To disconnect the socket with a clamp, the small screw-driver wring out a clamp(s), then disconnect the required socket section. Attentively examine the socket as often clamps of sockets are imperceptible at first sight. Many sockets have on some clamps.
At separation of the socket do not pull socket section in different directions for wires as it is possible to damage or pull out wires from clips of contacts of the socket.
