Installing/Wiring the Driver Assistance Switch:

- Power (Red) to Pin Slot #37
- Ground (Black) to Pin Slot #39
- Signal (Yellow) to Pin Slot #38

The DIY guide says use pin 37, 38 & 39 on A173*7B connector. But in my car I see those slots are already occupied.

Do anyone know which other system might be using those slots or those wire are lying somewhere unused on the driver side? if yes, how and where to find them?

Just an FYI ... I don't have LCW or LDW from factory.

Thanks in advance for the help!
Take your headlight control switch out. Check near that light control harness for another harness wrapped under it with those wrap tapes.

EDIT:

Look at this photo...you see the bulge wrap in the middle of the wire? unwrap that and take a look there.

Yes sir, I found the prewired connector for driver assistance switch wrapped with the light switch, exactly as shown in the image.

Thank you so much though
