Handling electrical circuits

If you want to find a fault in the electrical system or install additional electrical not do without a diagram showing the current flow and the cabling. The corresponding current loop should always be closed, otherwise the current will not flow. For example, it is not enough when the lights to the positive terminal voltage is applied and the outline on the contact mass is not closed.

Therefore, the mass of the battery cable is connected to the body. However, this earth connection is not enough, and the consumer has directly the corresponding earth wire whose insulation typically has a black color. The individual current paths may be embedded switches, relays, fuses, measuring instruments, electric motors or other electrical components. To be able to connect these devices properly, the individual cables have different colors.

Cable colors

The letters on the individual conductors indicate the color of the cable:

1 - symbol (Example)

2 - plain cable

3 - Black

4 - cable strips

5 - White (cable color)

6 - red (color strips)

Single letters denote plain cable.


B - black. In the two-color cables first letter indicates the basic color of the cable, and the second letter indicates the color of the strip.


W / R denotes the white cable with a red stripe. Consisting next letter in the brackets used to denote the corresponding cable harness.


(F) - Front cable harness in the instrument panel and the engine compartment on the right.

Symbols plugs

Plugs and jacks are indicated in the diagram as follows:

Identical connectors connected by the dashed line in the diagram. Plug without designation of color is colorless or white. Sockets that are not used are marked with an asterisk (*).

The compounds of the masses

Compounds in Scheme weight, usually at the bottom.

If the connection cable is carried out mass, a point indicated by the mass number. If the connection is made directly through the mass of the body, this is indicated in the diagram shaded point.
