The wiring is completed, now I will write briefly about the switches and buttons.
First, about the switches on the steering column. There are two of them in the basic configuration. On the left, there is a switch for turn signals and headlights. On the right, there is a wiper switch. For each of them, an additional option is provided in the form of a button on the end of the switch. On the left is a button for switching the indicators of the on-board computer. On the right is a button for turning on the intensive cleaning of the windshield.
An additional option is the third switch installed below on the right - the cruise control switch. I already wrote about this in the corresponding section, so here I will write only about the switch itself.
In the presence of an airbag, all switches on the steering column have a slightly different design of their levers.
Steering column switch


Part No. 1 - windshield wiper switch with an intensive windshield cleaning system (61 31 1 372 583)
Part #2 - turn signal and headlight switch and on-board computer (61 31 1 375 186)
Part #3 - screw M5X12 (07 11 9 906 816) - 4 pcs.

Part #4 - switch for fog lights and rear fog lights (61 31 1 368 895). In the basic configuration, this button is "single" (#5), - only for rear fog lights. If there is an additional option of front fog lights, a "double" button (#4) is installed.

Part #6 - lighting switch (61 31 1 376 001). Switches before restyling and after restyling have different connectors. There were other switches for the Scandinavian countries, with the "daytime running lights" mode. An additional K9 relay was also installed there, which automatically turns off the main beam when the fog lights are turned on. I already wrote about this earlier in the section on relays.
Part No. 7 - button (61 31 1 369 277). Switch handle.
Part No. 8 - switch cover (62 11 1 370 655). In my case, this pad also has an optional original wooden pad. I will write about this option separately.

Item No. 9 - the light switch of the drawer for small things. (61 31 1 386 316).
"Top" set of switches:

Connectors for the switch of turn indicators and headlights, and on-board computer:
1 - connector for connecting to the main wiring
2 - connector for connecting to the on-board computer wiring
3 - sound signal connector
4 - turn signal relay connector
5 - ground terminal
I have a switch for the US market, so it is missing the "parking" marker light connector. Unfortunately, this option was not available in the US, although it is quite useful. In it, the switch has additional "extreme" positions after turning on the turn signal, in which only one front and one rear position light bulb is turned on, on the corresponding side of the car. At the same time, the illumination of the number plate and the illumination in the cabin do not turn on. This significantly saves the battery charge during long-term parking on the side of the road. If I find it, I will definitely replace this switch with a "European" one.
Connectors of the wiper switch with the system of intensive cleaning of the windshield:
6 - connector for connecting to the main wiring
7 - ground terminal
Compared to the basic one, this switch has two additional wires going to the TS and PS contacts of the K10 wiper relay.
Cruise control switch connectors:
8 - connector for connecting to the cruise control wiring
The switches are screwed to the steering column. Their "mass" terminals are also screwed there. We connect all connectors.

The connectors of all switches are fixed with each other, and are latched onto the connector of the ignition lock fixed on the steering column. The turn signal relay is also fixed on the steering column.

By the way, in the photo you can see the white connector of the "parking" side lights that is not used. It will be necessary to use it.
Now you can install the plastic cover of the steering column. I already wrote about him in the corresponding section.

Not all the icons on the switches are well preserved, so later I will try to somehow restore them - with engraving or stickers... we'll see.
I almost forgot - we install the decorative ring of the ignition lock in the casing.

A trifle, but the look is much better with it! ;)

Then about the buttons.
