HID headlight wiring?

this is my first post but I've been searching around lately for detailed instructions on how to convert second gen prius to hid headlights. I'm completely new to modifications/wiring but I'm trying to swap out all the stock to led. I'm starting with the interior lights now. From what I've seen it doesn't seem too hard. I just haven't seen anyone explain the wiring, is there a forum ive missed or could some one help out?
