Some great schematics if you want to upgrade you aging wiring with relays.

There is also some good info on bulb types. What to use and why HID conversions are no good.

Good info. There is a lot of good info out there on why these trendy white/blue lights really stink. There is even a half an hour video out there with the light engineer for BMW that goes into a lot of this. He even admitted a lot of the choice to use them is just marketing. But good luck convincing someone that shelled out all the money of an HID kit any of this. They all just spit out "They work great, I can tell you because I have them." They can't admit they put out good money for the hype, and not performance.
