All this is assuming that your BCM can support OEM fog lights. A dealer will charge you ~$100 to re-flash.
The OEM switch can be re-purposed to toggle the bcm (link). This is cheap and easy. I used a passenger door wiring harness that had been cut after an accident to connect to the factory fuse box. Soldered that to the signal wire on my fogs and it worked like a charm.
