So I've installed halo lights in my GT fogs (they look sweet!) but I can't get the wiring quite right. I hooked them up to the battery, but of course they NEVER turn off. I thought about getting a switch, but I'd rather not have to worry about it.

Does anyone know a good wire to tap into in the engine bay?

 

Here they are. They came out great. Don't mind the hole in the top, you can't see them in the grille
