front wing side indicator disconnection and removal.

Evening All,
Just removing the offside wing on my 1997 Wolf and the proceedings came to a halt when I had everything off except the side indicator.

I felt all the way around it and couldn't find a tab to press.

So, it clearly something obvious, but I've missed it and I'd lost the light, so I thought a question to other Wolf owners (they are, again, peculiar to the Wolf) might help.

Thanks Mystery, that did it.
Which AESP is that in please?
I have several, but couldn't find it.

I must admit that I never considered looking in Operating Information for that.
Lesson learned and thanks again.
