In cars later than 72 (I think) the fog light loom is installed (at the factory) even if the fog lights themselves were not installed. Its under the cable hold down clip right below (or just to the left of) the hole where the fog light switch goes. No need to remove the headlight switch.
The fog lamp switch is third in from the headlight switch, to the right of the emergency flasher fob.
You may need to remove the knee pad to gain access to that area.
I found the FL wires in the front trunk so I am sure they will be under the dash. I saw the hole in the dash (covered by the vinyl) so I can install my new switch after it is connected. Maybe you will be right and I won't mess with the HL switch except for the tie-in to term. 15. I just want them working for now. I will do the "on without headlight" wiring at another time.
The fog light leads are tied down to the L/R horn leads behind the front bumper. The switch leads are under dash, below the switch. There is no need to tie to terminal 15. The only other thing you may need to do is add a relay on the back side of the fuse panel. Without a relay, there is no power to the loom so they [the factory] can place the wire ends in a place that won't short out. It's a simple installation. No wiring needed on later cars.
