one of other things i have done so far is install green underglow which was a complete bitch to put on seening how my car is low...we just jacked up each corner and built a platform out of bricks under the tires so we had enough room to work under the car 
we took the underglow controller and modded it and extended the switches to i could control them from my dash right under my head unit 
the last thing so far thar i have done is taken out the old interior light that didnt even work and made an led interior light to match my underglow 
i just took some proto board and cut it to fit in the stock houseing with a bit of dremeling and soldered up the leds and resistors and slapped it in and it works and pretty much looks stock when not on
