Wiring fog lights is easy, I presume you already have a foglight switch, the harder option would be to remove the dash and locate the back of the switch, then its a case of just wiring it to that, (earth, live, source) the easier option would be to wire up another switch, I have one for my neons in the change compartment to the right of the steering wheel, (the part you disconnect to find the fusebox) just cut a hole in that, and its easier to get behind it to wire it, plus its right next to the rubber part of the bulkhead to get the wires thru. If you want me to explain in more details, let me know.
