Also, the HID bulbs have four wires coming out of them:
1 red (which has a connector that attaches to the ballast)
1 black (which has a connector that attaches to the ballast)
2 yellow (where do these go? I know that the bulb has a HID low beam and a halogen hi..so the yellow must deal with switching the two or power or something..i'm confused)
can anyone help me out here?
