After I ordered my new 1.9 tdi se I realized front fogs were optional extra. Dealer price is a rip off to get these so I need to source some that I can fit. Can anyone tell me if the wiring look is in place already on these cars or do I need that too? If it is in place am I right in thinking I just need the fogs, dash switch and relay then I'm good to go or have I forgotten anything?
