i just got 2 xentec hid kits in. i know its plug and play and supposed to be easy. but im confused on where this wire goes.. do i need it or do i just hook up the the wire from the car to the ballast?

 

theres suppose to be plastic connectors on the end of those

 

You're gonna have to be more specific. What's this for? Looks like Its for fog lights to me. Plug the black pin in the side of the factory harness with a black wire, and the red pin in the side of the stock plug with the other wire, I think it's purple

 

i had those and didnt use them. but i did use these, they plugged into my gen4s.
