3. Most aftermarket HID units come plug and play, but you should get a relay harness anyway. The red wire on the relay will go to power, black to ground, the female socket takes one of your headlight plugs, and the two male sockets plug into the HID ballast. Then you simply connect the HIDs to the ballast and plug them in the headlights. The relay allows the ballast to draw power from the battery, as opposed from the stock wiring, which can be harmful in the long run, and also gives you a slightly brighter light and a solid fire up every time with minimal flickering.

4. There are a million vendors, but they're almost all the same. Mobilehid is the preferred brand around here. I ordered a kit from Umnitza in the classifieds, he has them for 65 shipped right now, and I ordered the relay from cliff at mobilehid for 20.
