Coloring of wires in electrical diagrams [Toyota Carina T170]

All electrical wires on a car are colored. On electrical diagrams, the color of the wires is indicated using abbreviations. The wire can have either a basic color or a color with colored stripes. The following letters are used to designate the wires:

• S — black
• G — green
• L — blue
• O — orange
• R — red
• W — white
• BR — brown
• GR— gray
• LG - light green
• P — pink
• V — purple
• Y — yellow

The wire designation "RG" means, for example, that it is a red wire with a green stripe.

All electrical circuits contain numbers in black circles. They refer to the names of certain parts and have no meaning when studying the electrical circuit.
