Nice mod if you are taking out the headliner for reupholstery.
Found a nice spot next to the rear hatch interior light to cut a nest for the controller.
Tapped into the same light for power, and the door lock switch becomes the on/off switch.
Got it from Amazon.. Mine is the 200 light kit, around $70.
The lights can be anything...Multicolor, all one color, built in mic that chases with music, really cool.
Pictures don't do it justice. In person they look really sweet.
