I own a 2011 B8 A4 S-Line from North America and I purchased a Euro folding mirror kit from ECS Tuning to have a shop help me install: Link/

It should be plug and play, but they sent me a picture of a wire for which they could not identify the outlet, and wasn't found on the stock part. Would anyone on here know where to insert the orange and light-blue wire? Thank you.

Edit: My vehicle does not have lane assist. Could that wire be for lane assist?
