I looked it up online and found what it is called it called a "add a line fuse" I got mine at advanced auto but here is a web site that sells them so you can see what they are ATC Fuse "ADD-A-CIRCUIT" You just plug it in where the factory fuse is for your fogs. It is in the panel on the side of the dash. I forget what fuses I put in it but you just need two of what ever the factory fogs take and then you will have a hot line out when you turn on the fogs. The great part of it is if you dont like it you can just move it to another fuse and just use your remote to turn them on and off. There is one down side to running them threw the fog switch you cant have them on when you have your hi beam lights on. If you want you can look at my gallary I have pics of them on my car I think they look good myself.
