So I got a free set of some off road Sylvania square lights to mount on the truck, but I am having a hard time finding a wiring kit or harness for it. It didn't come with one, and I want to run a toggle switch similar to this (<~~click!) one. Can I get any wiring kit to work with them, or do I need a specific one? There is only one wire coming off of each of the lights, so I assume the wiring kit will have to have a separate ground.
