Circuit diagram
For the electrical (circuit) diagrams for DAF vehicles refer to the Sales Engineering department at DAF. Also the local DAF dealer has electrical diagrams available in the workshop manuals.
If applicable, the bodybuilder should make additional circuit diagrams available, which must be added to the other documentation required to be kept in the vehicle. In the event of breakdown and/or repair, this permits more efficient working.
Marking of wiring
The marking system consists of a numerical and a colour coding system, according to which the wiring is clearly classified, and connection and manufacturing errors are avoided.
The numerical coding consists of four figures, the first figure of which refers to the main group and the colour.
