I've done several OEM interior modifications as well, these include the High Pixel cluster as seen on earlier pages, as well as a leveling rheostat switch for aiming the headlights.
I also have a euro light switch which has city lights, low beam as well as front and rear foglight settings. I have a rear foglight as well as a 5 brakelight mod. I have also wired the rear foglight icon in my german instrument cluster.
I have a full set of blue led lights inside, as well as a W8 sunroof panel. The panel has red ambient lighting like a BMW, and also has better lighting than the stock panel.
Hatch lighting courtesy of Varad 12" white LED bars.

I had a problem, fuse 14 was blowing whenever I'd unlock the doors with the hatch open. Thanks to a tdiclub member, I checked under the rubber wiring conduits and found this...

Got my Alpine 9835 installed this week, it's a seriously nice headunit.
