I am wondering what wires do what for.my headlights there is 3 of them.

One looks to be purple with a white stripe
Another is red
And lastly there is a red with green stripe.

Which one is positive and negative for lows? I got a cheapo hid kit given to me and I wanna try it out. The kits for 9004/9007. I believe its wired for 9004 now

 

All 9007 HID kits I've seen come prewired setup as 9004.

This should help you:

 

Thank you!
