The foglight, and I think headlight, wiring goes through the multi-function switch, so you might want to pull that apart and check the connectors there...
Here's a diagram I found on one my favorite sites (www.veryuseful.com) of the hedlight/foglight wiring. Note the foglight circuit has been cut and rewired with a standard 30 amp relay to prevent the melting of the connectors and overheating inherent in the Fox GT wiring...
