Here was the link that popped up is this place legit The Retrofit Source | The Best HID & LED Projector Headlight Upgrades
Or is there another place I should order them from
Great that is their local dealer, if you don't have am aftermarket fusebox give these guys a call and explain to them that you are running the power wire all the way to the battery that is in the back of the vehicle and they can help you come up with a long enough power wire extension unless you are comfortable doing it on your own.
