I'm assuming you're referring to the LED foglights that come on the upper trims? I have a Blue as well and I don't believe the factory foglight harnesses are there to begin with so you'd have to do some custom wiring and because of that, I won't do it.. I was hoping for a direct swap-in OEM thing.
This can be done but the entire bumper harness must be changed. In the us that harness is $238 plus bumper trim plus lights. It was going to be around $600 to do my wife’s car, so I’m going to wait until I can find a harness salvage.
