Install electric adjustment of the headlights range

Post by joaoavr »

Hi

I have a Polo 9n here in Brazil and it does not have the electric adjustment of the headlight range. So, I want to install it in my car.

I bought the servo motors (1j0941295b) and the headlight range control, instrument and switch lighting (6q0941333C).

According to my research, the headlight pins 1 3 5 are for the electric adjustment of the headlight range:
pin 1 - positive low beam
Pin 3 - Ground
Pin 5 - positive headlight range control

I still need the following information:

1 - The correct connector and the connector pin of the firewall to connect the wire (6q0937403a)?
2 - Where is the headlight grounding point for me to connect the servo motor ground?
3- What are the wires for pins 2 and 4 of the headlight range control connector (6x0972926)?

Can you help me?
Greetings from Brazil

For the 6Q0 dimmer, I think it is:
1: GND
2: output to headlight pin 2
3: input from light switch
4: input from the headlight dipped beam (positive)
5: output to 58d (instrument lighting)
6: empty

For the headlight:
1: input from the headlight dipped beam (positive)
2: input from the dimmer pin 2
3: ground

Thank you for your help!

If you can help me some more:
- Where does the yellow wire from pin 4 of the 6q0 dimmer come from?
I saw this image on the internet, but the headlight switch doesn't have a completely yellow wire. Yellow / purple only (pin 7), and yellow / white (pin 8)

- Where is the GND point of the headlights?

The pin 4 of the dimmer comes from the fuse of the left headlight
The ground of the headlight connects to the brown wire in pin 5 of the headlight
