Which wires on the factory fog light switch will I need to splice into? I'm still trying to make it all look as OEM as possible.

Use a multimer and ohm it out. I think its green and green/white. They are the actual switched ones. I just did this not too long ago.

Also, non fog cars are not wired into the engine bay for lights, thats why you cant find the harness :)
