^ FWIW wire them yourself, the stock wiring while adequate is just that-adequate. I have very powerfull lightbar on my work van that we totally wired ourself with all 14 gauge or better wire. No chances and its held up great. I also wired all my offroad lights, all 14ga too.
Thicker the wire better you are so long as you dont go nuts. Most stock wiring its 18ga and imho barely enough.
