you could always run it through an inline fuse and relay to a switch. just connect the inline fuse to the battery or 12v source and of course a ground. then the relay to the switch and part of the light. do this for each light. I think autozone and advanced carry foglight kits for like 7-12 bucks ... im not sure on where they are on the ls but hope this helps

you dont really have to get a fuse holder and a relay. BUT to be safe u should wire up a fuse to the power wire just in case to prevent anything from burning up or catching on fire.

the relay is also a choise also. if ur worried about forgeting to turn ur fogs off than u should get a relay also.

i wired my fogs up pritty similar to the diagram but i didnt put a relay in. so whether the key is in the ignition or not i my fogs will stay on. im going to put a relay caz sometimes ill b running late to class and 4get to turn em off haha

i cut the conector off that you plug the bulb wires to. its a power and a ground wire. then i ran my own wires to the battery. from the battery to the switch i put inside the car. i didnt tap into any wires the way i did it

Fuse for the fog lights for UCF10/11 is located in the fuse box under the steering column.
