If you have a moonroof then the mod is easier because you can run it along side the moonroof and not have to struggle as much getting the wiring from the back to the front. As far as the light itself goes, it does have an "on/off" switch which can be set to turn on when you open your doors. However, you can't control it from the front lamp. There is a wiring harness that they make for this mod which I believe costs around $20 and may make your life easier. I just used two lengths of wire, taped them together and ran them to the front lamp. Good luck!
