The stock button is just a push button that connects to the BCM. The BCM commands a relay that runs the fogs.If I get ahold of the OEM switch how hard would one think it would be to wire these in?
How easy depends on if the programming is in your BCM and if the wires are all there. I think there's other threads about adding fogs, so I think it's do-able, but might take a trip to the dealer.
