I would recommend checking the fuse for the fogs.

If you look up the bulb number, it shows them as 24 watts each. That comes to about 1.77 amps each at 13.5 volts. I looked for the fuse, but couldn't find a separate fuse marked "Fog lights". Figure they sized the wire for about double the load 1.77 x 2 (lights) = 3.54 amps (load). I'd try to keep the load under 4 amps on the fog light circuit. If you want to run more, trigger a relay off of the fog light circuit and run a heavier power supply wire.
