just fitted a set to mine, i ran a live and eart from the plug in the corner, down to n/s fog then continued the same wires over to the o/s fog.
The one thing i did do was to fit a relay in the fuse box, for some reason vw didnt put one in, the socket is there and connected. btm left of relay plate/fuse box.
the fogs only work with ya headlights on, not with ya sidelights.
Cant legally be on without dipped headlights.
If you want them on without, you will have to fit a seperate switch and extra wiring and relay.
Most accesory shops etc do complete wiring kits with all the neccasery parts.
Good luck, do it proper an ya wont come a croper
