Hi Tony. I have a 1999 Focus CL and had the same problem as yourself. The extra wire for front fogs was in the plug that connected to the light switch. After hunting for ages, I concluded that the loom for the fogs wasn't there and had to make one. I have no idea where that wire from the light switch goes. I couldn't follow it without taking the dash apart and I wasn't going to do that so I ran a wire through the firewall and used a skotchblock to join it to the foglight wire on the switch and it all works fine. I'm afraid you'll probably have to do the same. Hope this helps!
