If you don't have fog lights. How hard is it to install it? I mean the glasses are already there and I have the button in the car. And probably some wires are probably already there.

Is there any guide?

 

You have the foglights already installed? But NO bulbs in them? Or is the hole empty where the fogs go?
Install takes about an hour. Gotta remove 3 push pin plugs under the front bumper and pull plastic down. wera long sleeves cause its gunna tear up your arms.

 

I don't know if there are any wires, couldn't see any. Is there wires for fogs on all Z28:s?

 

Does Camaros come with wires for fog lights or was that an option?

 

It's an option. Either you have them or you don't. Sounds like they came equipped on your vehicle.
