Mount the light bar, then raise the center section of your hood, there will be a group of wires under there that have the female end of a bullet connector on all of them. You will need tie into those because they go through the firewall and the other ends of those wires are behind your panel where the ignition switch, and other rocker switches are. Remember which colors you tie into. There is a bus bar with two studs behind the panel you have already popped out, left side is ground, right side is hot with the key. Follow the directions that come with the light, you will have one hot for the light bar, one hot will be for the driving light that will come on when the switch is on, other one is the ground. If you get your rocker switch off Amazon follow the direction that comes with it. Pretty simple plug and play, hide your harness the best you can. There are two holes beside each other under the hood, I used those holes to mount the relay's. I will comment of the back light later today. Good luck, don't let it intimidate ya.
