it was so easy to wire, that's if u dont want to be fancy and have a little switch from the inside to turn on and off.
i had one strand of wires put together directly from the lightbulbs, positive and negative wiring, and it was all linked together and had an outlet to plug into another set of wires, but i said **** that.
so i cut the whole thing right in the middle, one side had + and - wiring connected to the light and visa versa with the other side. i grounded them to a bolt, and spliced the positives into my lowbeams. thats all there is to it. its not going to blow up or anything, so no need for a relay. i've had it like this for about a month and still doing good.
