The additional block of the relay

The additional block of the relay (3) is located under a shelf (2) at the left under the instrument panel. The naklennaja tablet (1) shows, on what place what relay or what block of management is located. Their position varies from the car to the car.


For 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 контакными connections for various plaits of cables are located. For example, at дооснащении here it is necessary to connect a plait of wires, the uniter antifog headlights and the switch.

The relay or management blocks for which there was no place in the central switchboard, are located in the relay block under the instrument panel. They become accessible after shelf removal at the left under the instrument panel. The arrangement of contact cells shows drawing below. There adapters are noted also additional, meeting not everywhere.
