^^^thats it. You have a transformer (the little black box with 4 sets of +/- slots). This gets wired to the battery, and to a switch. I mounted my switch in the dummy slots on the dash. Mount the lights under the car, run the wires to the transformer, hiding them and tucking them and mounting them so they have no play. This is important. Put all the wires inside looms for two reasons...One if you get moisture in the wiring or bulbs, they will burn out. Two..it will get the wires from rubbing and shorting out. The transformer I mounted down behind the drivers side headlight. Its not hard to set up all the wiring, etc. but the more time you take insulating, looming, hiding mounting etc. the longer your system will last. I learned the hard way, I have had three complete sets on mine. Moisture is definately the enemy. Oh, some systems come with a way that the lights run from one light to the other in a series and not all four into the transformer. Same basic concept though. I hope this helps. Just take your time.
