Dome Light Wire Location
 

I recently installed some LED's in the footwells, but was only able to ground them to the driver side door. Meaning that they only turn on when I open the driver side door and turn off when I close it.
I have looked throughout the internet and googled multiple variations, but haven't been able to find what I'm looking for, hopefully you guys are more knowledgeable.
I'm looking for the location of the ground wire for the dome light (aka ceiling light, interior lights). I would like my LED's to turn off and on along with the dome lights. Thanks for your help in advance. :)

oh, I own a 2005 HCH
