Additional block of the relay

Seldom when all cells are occupied, but cells with the first on the sixth are provided in each car. To the right of contact cells cells with demountable kontakny connections for various plaits of cables are located. For example, when retrofitting it is necessary to connect the plait of wires connecting fog lights and the switch here.

They become available after removal of a shelf under the dashboard at the left. The arrangement of contact cells shows the drawing below.
