For ease of use, all electrical circuits on the wiring diagrams are arranged vertically and numbered.
At the top of the diagrams, a fuse and relay box is shown, bounded from below by a horizontal line. The thin lines above it are the inner connections in the block.
The horizontal lines in the block numbered 30, 15, X and 31 are the internal connections of the block with power supplies and «weight». Circuit 30 is constantly under battery voltage, circuit 15 is only when the ignition is on and is powered through the ignition switch. Circuit X is energized also when the ignition is on, but when the starter is turned on, it is de-energized. Circuit 31 connected to «weight».
At the bottom of the diagrams there is a horizontal line that shows the connection to «weight».
Circled numbers near the intersection of vertical chains with a horizontal line «masses» indicate the location of points «masses» on the body.
The number in the white square at the end of the vertical chain indicates in which chain you need to look for the continuation of this wire. The colors of the wires in the diagrams correspond to the colors of the wires on the car. The number on each wire means the cross-sectional area of \u200b\u200bthe conductive core of the wire in square millimeters.
The number in the black square indicates the number of the relay in the fuse and relay box, the letter in the circle next to the wire indicates the permanent connection of the wires.
Internal connections (thin lines) - such connections are not wires, but electric current flows through them. They make it possible to trace the path of current flow inside electrical equipment.
Terminal 15 - when the ignition is on, it has battery voltage.
Position number of the relay – designates the relay, designates the number of the relay on the additional relay panel.
The wire cross section is given in mm2.
Element designation - allows you to find the name of the element represented by a graphic symbol in the list.
Wire color - matches the color of the wire in the car.
Contact designations - on the relay, control device and on the board or additional relay panel.
Alphanumeric designation at the connection points - determines the position of the wires in the connectors (M30az).
The numbers in the boxes - indicate the interruption of the circuit and set the number of the current track of the continuation of the circuit.
Alphanumeric designation - marks a plug-in connection (T8a/7).
