Project: Volkswagen Polo 6R Automatic Headlight Sensor Activation
Project Car: Polo 6R GTI
Matarials used:
* 3C8941431A - AUTO Headlight Switch
* 8E0971980 - 10 pin connector
* 000979009E (6 pieces) - Pinned Cable
* 1K0951253 - Relay
* VCDS & VAG-COM Cable
First.
Headlight switch is while 0 position, turn to right and remove.

New Headlight Switch
![[Image: 34CXjdH.jpg]]()
![[Image: eU1yJLE.jpg]]()
Original Polo Headlight swtich is 17pin socket, but new switch is 10pin socket.
For this reason, we have to re-wiring on the new socket.
10 pinned socket and wirings...

Next step: Relays...
We build between 85 and 86 diodes.

Next step, installed headlight switch wiring...
Which is connected by cable to where I draw the diagram.
After all these old installations and new installations have had two sockets for headlight switch![smile2 smile2]()
Upper Circle is New Socket,
middle circle is old socket ( no longer need )
below circle is relay box.

Next Step...
BCM Wiring...
BMC Location:
![[Image: CUgK3Yl.png]]()
![[Image: dmVjnBv.jpg]]()
BCM have two connector,white and black.
Black is A, white is B Connector.
our operations will be on A.
2. pin to BCM A CONNECTOR 37. pin
relay 86 to BCM A 1. pin
