Ok, you have some choices to make then.
You can more easily wire your own fog lights using that switch, from and independent power supply, or you can see if your BCM already has the fog light logic and wire it the stock way.
Are your familiar with the BCM or would you rather just make your own simple circuit?
If you have the holes for the fogs, buy them and add them in, in my case I don't, I will be adding some LED strips in the lower groves as I do not have those holes. (this is why I ask about the bumper)
