Additional block of the relay

The additional block of the relay (3) is located under a shelf (2) at the left under the dashboard. The Naklenny plate (1) shows, on what place what relay or what control unit is located. Their position changes from the car to the car.

On the additional block of the relay you will find the plan of an arrangement of numbering of contact cells also on electroschemes. 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, at a doosnashcheniye here it is necessary to connect the plait of wires connecting fog lights and the switch.

They become available after shelf removal at the left under the dashboard. The arrangement of contact cells shows drawing below. There adapters are noted also additional, meeting not everywhere.
