it's independent of the SX lighting system. Mine's an EX, but it comes with its own button which goes in front of the cup holder in what i call the wallet holder. they turn on/off automatically when you turn the car on/off. you change the led color by tapping the power button on the LED kit.So does it come on automatically and is it controlled by the same interface as the mood lighting on the doors? My concern is that I don't want to have to deal with multiple controls and I don't want it to be a completely different color than the rest of the mood lighting. I do however like the fact that it lights up the cup holders as that was a complaint I had although not a huge deal. I just had light rings in my Jeep Grand Cherokee and really liked that at night.
