Here's exactly what I did: I tapped the "switched" wire for the stereo, pulled the wiring through an existing grommet on the "firewall" and connected it to terminal #15 on the fog light switch. The black/blue connection coming from the defroster switch to terminal #58 is for the dimmer illumination light that comes on with dash lights and remains unchanged.

I did mix up the ternimals and connected switched source to "I" and the lead going to fog light relay to "III" and it still worked, hence the reason I was confused with my own wiring at first; according to the wiring diagram it makes no difference whether you connect the switched source to "I" or #15. I'm not entirely sure the switched lead for radio is fused or not, so probably best to put an inline fuse when you add the fog light switch to the circuit.

Hope it helps!
