Hey guys

I am trying to install "puddle/ghost lights" or "courtesy/shadow lights" in the doors of my 2014 buick verano. I was able to get the door panel off without problem but am now stuck on which wire to attach these suckers to so they will cut on when my door is open. I am thinking either the dome light or door trigger. Does any one know the color coding for these wires in the door?? or have any suggestions?

Thank you!
