Just as a tip, the reason for the relay is because most switches won't handle the power the lights will consume and start fire. That is why you hear a relay click when you turn on your headlights. So you wire the switch to control the relay that in turn controls the lights. You can hook the 12v+ that goes to the switch to an accessory power(only on when key on) , but then you can't turn the lights on without the key to say, set up camp. You can get a kit for it with the relay,switch and wire for usually less than $20-25 or if you know what you need you can buy parts separtely for under $10.
