My Start Button and Aux-In mods
Ok, I know these aren't performance enhancing, but the aux-in is awesome (especially since I hate Dallas radio but want to keep the factory unit) and the 'Start Button' mod is just fun...

I had already done the aux-in mod and loved it. I wanted to do the start button, but hated that most folks put it in the cigar lighter spot. Too low and too far on the passanger side for my taste. So... I decided to combine the two mods into one unit. I sketched out a new tray unit to replace the one that was under the radio and had a friend machine it (he's a model maker and runs a shop with several CNC machines :D ). The button is in a factory-looking beveled hole and the tray now has a door that can be closed to hide whatever is inside (like my mp3 player). Since there was extra room behind, we made the tray deeper so you can actually fit things in it. I'm pretty happy with the way it turned out! :D
