Purpose of relays and fuses in the engine compartment
Connector markings
The connectors are divided into groups according to their location on the vehicle and have symbolic designations.
Wire marking
Wires differ in the color of the insulation and the cross-section of the conductive part depending on what electrical devices they are connected to.
The diagrams indicate the wire marking with a letter code.
- F – wire type (flexible wire); T: twisted wire.
- 1.25 – wire cross-section in mm. If the value is not specified, the wire cross-section is 0.5 mm. If the wire color code is given in brackets, the wire cross-section is 0.3 mm.
- G – main color of the wire.
- B – additional wire color.
Color coding
With a two-letter wire insulation color code (for example, RG), the first letter indicates the main color of the wire (red), and the second letter indicates the color of the stripe on the wire (green).
The electrical circuit used depending on the color of the wire insulation
