I added one I removed from a SEL. The SEL are the ones that are standard with the Rear light. I removed it from a local U pull it yard and traced the opening onto a piece of cardboard took it home and installed. Youll nee to extend the front dome lights to the rear. I did not remove the headliner but i do suggest taping the wire down it WILL rattle. I also have a sunroof which made it easier to route the wires i just ran the wire next to the sunroof opening and you black duct tape. If you need pictures let me Ill take em and post em if needed
