i did this on my mk3 TDi. Got the lights, blancking plates, and a switch. You then need the wirin loom. Not as bad as it sounds! There is a large connecting plug at the front of the engine bay (top left of the rad as you look at the car) Undo this and remove. This includes the headlights, indercators, and the horn I think. Then replace with a new loom from a car with fogs, replace the switch et-voila!!!
Took less that an hour!
