I still need to wire mine up. You will need to have an accessory witch available on your panel. If you do not, you will need to add a switch. I need to draw it up so you can understand what I am talking about the wiring. It really is not hard at all. It all depends on how many lights and the total wattage of lights you are using. If the wattage exceeds the switch allowable, then it is wise to use a relay. Again, i will draw this up so that you can understand it better. Trust me I am an electrician.
