ok, if you want to do fogs, then just get a kit with 880 bulbs and put it in. You will connect signal wires to factory fog light connectors for each side. As for headlights, it depends on what kind of HIDs you want: bi-xenon, single with hi-beam halogen, just single xenon for low beam and nothing for high beam, dual xenon, or whatever your imagination allows you. For some applications you need relay harness for others don't. But one thing i can tell you , if your lenses are foggy, there will be a very little difference if you switch from halogen. If your lense is clear, there will be a **** of a difference. Some say that HIDs in headlight housing blind oncoming traffic, but I just put headlights a little lower on one of few cars that I did work on and that helped. IF you don't want to lower your headlights, open them up and paint lower part, where reflector is, black and that would help. Or make vinyl eye lids for your headlights and that does the trick.
