Fog light wiring, Are these the right ones? Options

[Chad911sc]

Spent the last week refinishing the ground effects and the bumpers. Next step is to put fog lights back into the factory spot. I have the new 914 Rubber fog lights grilles and led lights to fit, but need to know if these are the right wires. And also if they are, how are they operated? Not sure if this car came with them from the factory, the car already had aftermarket plastic grilles in it and they were cracked and broken. My interior only has one light switch that is a pull switch that activates the headlights. I put my volt meter on the brown ground and the white/yellow positive, and no voltage going to them when light switch is pulled out. Are these the factory wires, or something else?
