If you need a relay, go to your local Radio Shak or something similar and get a 4 pin relay and a relay holder. You CANNOT wire aux lights without a relay, otherwise you are sending the current necessary to run 100 watts of lights through a thiny little plastic switch in your dash. You will end up with a fire. What the relay does, is send a SMALL amount of current to the switch. When the switch is flipped, it completes the circuit, trips the relay, and the RELAY sends the current necessary to the lights, not the switch.
Do a google search for AUX lighting schematics and you should get a good idea of how to run them really quick. I used radio shak relays/holders for my lights and just zip tied the relay holders to the engine bay brace. After awhile I ended up buy a sPOD. If you have the money, the sPOD is DEFINITELY the way to go. I lucked out and was given a used one (the old model, the person upgraded to the new model) for basically nothing. Even though it is the old model, I am still blown away by the product.
