I just picked up a 50" LED light bar to put on my TJ, but I don't know much about wiring. As far as I know, I need to ground the black wire to the Jeep somewhere and attach the red wire to the positive terminal on the battery (picture 2). Then find a good location nearby to mount the relay. After that I have the little plug in pictures 3/4 that I'm guessing I some how connect to the black/red wires coming off of the light bar that are just hanging there. If that is correct, what is the best way to connect the two? Sorry for my ignorance, thanks for the help.
