How to Wire Below Bumper Fog Lights

I have a 90/91 Cabrio, it has the standaed fog light switch with two settings. On the scirocco the first setting activates the front below bumper fog the second setting the rear. I have aquired the fog lights and need to know from what point I need to access the loom to connect them to the switch or is all the way back to the fuse box. Any help appreciated. Ragtopdave.

if the car had them as standard you may find the looms still there by the headlights there just 2 pin plugs iirc :wink:
