1 – line of conductors of an assembly payment of the main assembly unit:

30 – the positive conductor connected directly to the rechargeable battery without safety lock;

15 – the positive conductor connected to the switch (lock) of ignition without safety lock;

X – the positive conductor connected to the switch (lock) of ignition without safety lock.

2 – splitting an assembly payment of the main assembly unit. This splitting includes safety locks, the relay and sockets.

3 – the instruction on continuation of a wire or the scheme.

4 – symbol of a point of accession (plug) to an assembly payment of the main assembly unit. It can be used as an auxiliary symbol at the link to the assembly block. For example, E/8 designates the eighth plug of a block E assembly blocks.

5 – contact designation. This designation is usually applied on an electrical circuitry component.

6 – marking of continuation of the scheme or wire. Number in a square frame corresponds to serial number of continuation of a wire on the electrical circuitry.

7 – internal wire. Is present at the image of the internal scheme of a component of the electrical circuitry.

8 – serial number on the electrical circuitry. It is used for search of components of electrical circuitries and connecting points of the "broken-off" wires.

9 – a point of connection of wires in a block.
