Genuine ones ?,
After Market ?
If its genuine ones, the wiring loom should be there in place,
if not, go to a wreckers and get the fog light looms, and the switch to suit,
Where to turn the fog lights on, you have to pull the headlight switch towards you, and green light will illuminate on the dash,
you may also need to check if there is a globe installed in the cluster for that model/varient you have.
So there is a number of things to check before you start your project.
