The wiring's there, it terminates in a white (or it was when it was built) clipped about 7-8" above the foglight. Get underneath and have a nose around on the driver's side - it's a bit less crowded - with a torch and you should spot it. If you get the original foglights they come with the plugs attached.
To fit them it's a lot easier to take the bumper off.
However, if they weren't fitted at the factory, the circuit won't be switched on in the BECM. The check light will come up on the foglight switch, the wiring will be there for that as well, but the fog lights won't come on.
