Need wiring help

I am wiring for lights in the front door panel reflectors. I need to know what wire powers the interior lights when opening the doors.

Catch the interior lights in the footwell lamps. Polarity isn't a concern unless LED's are used. These will act just like the interior lights with a soft on/off.
