Need dash light wires in headliner

[LaserBlueZ71]

I am about to start my AUX switch project where I will be installing 7 AUX switches in my overhead console. These switches have an indicator light in them. I want to tie them into the same lighting that is used in the overhead light switch. This way, the indicator lights on the AUX switches I am installing will turn on/off with the dash lights, and also respond to the dimmer.

 

Does anyone know what wire(s) in the overhead console power the back lighting for that door lighting switch that is up there? I figure if I can tap in there it should be pretty easy.

 

Thanks all!
