Is it easy tO install fog lights on vw cc 2012

Not at all difficult. www.jcwhitney.com/...2012-volkswagen-jetta/...fog-light/... has them

It's just as easy as any other car. Go to eBay and find a set that are the sized and shaped to fit your application. Mount the lights and run the wires.

Do I need to do any additional wiring ?

I ask dealership they ask $750 to install them

You can also buy them from the dealer, genuine factory ones

You can do it yourself if you have any rudimentary mechanical skills at all and a few basic tools

I do just I don't know should I have to pull wire for the switch

That is a good question..since it was an option, there may be already a wire(s) in the loom under the dash. See if you can tell without having to rip everything apart...wires in a loom that have no "home", and there s probably a blank spot with a plastic cover that can be take off for the switch

I found original switch with fog lights but I didn't see and wires behind the grille

Well, if not there, should not ne real hard to run them, and make them sanitary, Time consuming, yeah..

Ok thank you
