Bmw F46 halogen to led

Hello,

Can anyone help me with electric schemes on F46!

I am on swap halogen headlight to LED headlights.

I can't understand how to connect pins 9 and 10.

With all other pins seams everything clear, just swap location in terminals.

P.S.

This is info from another forum on retrofit halogen headlight to LED on F45 almost same way:

For the LED headlights themself you don't need to run wires (except one ground), you can use the wires already there, just swap the locations on connector and BDC. Remove the wires from the connector that you don't need and tape them to the cable bundle. (I have cut them in different lengths and taped them to the cable bundle so they'll never touch).

Here is the full pinout:

LED Headlights ---------------------------
Lamp Right:
- Pin 1: Indicator (already correct)
- Pin 2: Ground (already correct)
- Pin 3: TO FUSEBOX Z7 CON8 PIN 6 (20A) (use an existing 2,5mm2 for this)
- Pin 4: Run a wire to a nearest ground collection point. There is on near the headlight where all ground (brown) come together.
- Pin 8: BDC CON4 PIN 53
- Pin 9: BDC CON8 PIN 44 (CAN H)
- Pin 10: BDC CON8 PIN 43 (CAN L)

Lamp Left
- Pin 1: Indicator (already correct)

- Pin 8: BDC CON4 PIN 54
- Pin 9: BDC CON8 PIN 44 (CAN H)
