If it is necessary to define malfunction in electric system or in addition to install electric fittings, not to do you without scheme of connections. On the basis of it reveal a way of passing of current and, thereby, connection of wires. The corresponding electric chain has to be closed, otherwise electric current can not proceed. It, for example, is not enough when on the positive plug of a headlight tension is applied if at the same time through connection on the case the electric chain is not closed.

In separate electric chains switches, the relay, safety locks, measuring devices, electric motors or other electric elements can be installed. Switching details with the corresponding coordinates of positions are given in the explanation to the scheme except the scheme. Each scheme of connections is divided into search fields by letters (from And to M) at the left and right edge, and also figures at the upper and bottom edge. The found communication detail of the scheme is in a point of intersection of the meaning horizontal and vertical lines proceeding from the corresponding letter and belonging to this figure which in the form of coordinates of a position are located in the explanation behind a scheme element.

Versions of the car and special equipment are framed with the dash-dotted line and noted by a symbol which is given in the subsequent page or in the corresponding explanation. The direction of the movement is presented in the scheme by a symbol "X". Figures on junctions of wires with consumers, switches, etc. coincide with marking of these details in the car. At the same time a little big figures specify marking of plugs of a separate electric chain. That it was possible to track passing of wires better, separate connecting wires have various coloring.
