Note: All switches and contacts are shown in mechanical rest.
1 - Terminal designation 15 - battery voltage is supplied when the ignition is on.
2 - Internal connections (thin lines) These connections are not made by external wires, but by conductive connections inside the blocks.
3 - Pin designations on the relay/control box and on the relay card/additional relay box - eg 17/87 = on the relay card.
4 - Relay pad number indicates the relay pad number on the relay board or optional relay box
5 - Wire cross section in mm.
6 - The color of the wire matches the color of the wire in the car. Here: green white.
7 - Designation of a group of elements. With the help of it, they are found according to the legend, which means a conditional symbol in the diagram. Here is the radiator fan.
8 - Designation of the element whose image is available in the current circuit
9 - This field indicates the relay board with fuse holders.
10 - Alphanumeric combination next to the pins of the connector, shows the connection of the wire in a multi- or single-pin connector. For example. B 15a - multi-pin connector B. pin 15a.
11 - The numbers in the square show wire interruption and give a link to the current loop where the continuation follows.
12 - Switch symbol. This is the reversing light switch.
13 - An alphanumeric combination means a detachable connection. Here T4 is a 4-pin connector. Designation T14/12 means T14 - 14-pin connector. 12 = pin 12.
14 - The numbers in the circle indicate the location or position of the ground connection point (see legend).
15 - Vehicle weight.
16 - Current circuit number to facilitate finding elements on the electrical circuit (see legend).
