Help needed - wiring B7 RS4 headlights

Hi guys, so if you’ve seen my build thread you’ll understand what I’m trying to do.

I’m in the process of making my own wiring harness to run B6 bi-xenons on a B7 loom. I’ve done everything else but have pin 11 on the B7 side with nowhere to go on the B6 side.

What does pin 11 control on the headlights??

Blue with red or pink color.

My B6 lights were converted over to B7 Lights. Not sure if it will help but I’ll take some pics of the wiring for you. Unfortunately I won’t be able to take pics until Monday or Tuesday.

I know you’re going the other way but I’ll take some for you just in case it’ll help.
