Sportback Rear LED's

Hi all,

I got myself some LED rear lights for my audi A3 2007.
I fit them and connected the Kufatec adaptors.
I noticed on the inner lights there is 1 wire on each side that needs to be soldered to the license plate feed.
The issue I have is I cannot find any pictures showing which wire that is.
Can someone be so kind and post a picture showing which wire it is exactly before I butcher everything?
