Does the light kit just light up the cup holders and the two footwells like the picture?
How do the LED lights mount into the cup holders?
Yes the way the kit is designed it just does the footwells and cupholder. One thing I noticed on a lot of the Ford sites was how bright they look in their photos. Trust me they are not that bright and overbearing, just a nice subtle "mood" light.
Here is a pic I found showing a Navigator with it. Notice where the cupholder light is, you have to drill ito the cupholder and put a hole in the rubber liner too.
Also, I referred to the following thread for install ( it's for a F150 but you get the idea, also the wiring is incorrect for an Expedition ) I also have a copy of the Ford directions for an F150 but not an Expy.

I will try and get a couple of pics of mine tonight.
