rear blind switch query

[topgolfer1]

Hi,I am using a rear blind switch to operate the garage door opener as I have a spare slot in the dash,and had this set up in my old A8,and I really miss the convienience of it!!!

My question is, does anyone know which of the switch pin outlets, on the back are for illumination?

I know pins 4 and 6 are for the garage door remote.that works fine,its just it would be nice if it illuminated.

Cheers

Rich
