Adding Footwell Coutesy Lights and A Glovebox Light

[Broosedamoose]

I want to add LED light up under the dash for courtesy lights as well as add one for the glove box. I'm trying to find the wire I need to tie into that becomes hot when the doors are opened and the dome light comes on. The glovebox light I can just tie in to any 12v source. I just can't find anywhere to tell me which wire I need to tie into for the courtesy light. I'm thinking about adding them under the seats as well. I want them to come on when the door is open and off when closed.
