NO NO NANETTE!! The parking lights, and a bunch of other lights go through fuse 14 (at least in my '89), which is 15 amps. I suspect your fogs are 55 watt bulbs, which is (2*55 watts)/12v=9 amps. This does not leave much for everything else, and as a bonus, you might cook your headlight switch.
You need to wire in a separate circuit with a relay. You get the control voltage from the parking light circuit, then run a 10 or 12 gauge wire (with a 15 amp inline fuse) from the battery, through the relay, to the fog lights. The relay functions like an automated switch, with the low power (the voltage in the parking light circuit) causing the relay to close, which directs the high power from the battery circuit to the lights.
Especially don't mess with the circuits that go through the headlight switch. It might not fail immediately, but the switch is the weak point. Our cars do not have headlight circuit relays, so everything goes through the switch.
You might want to consider putting in a separate control switch for the fogs, rather than having them come on with the parking lights. I'd love to be able to flash other cars sometimes, but because of the retractable headlights, it's a chore. That knockout in the dash by the cruise control switch is where the OEM fog light switch goes. I bought one from a member here, or you can get them on eBay. If you did it this way, you might be able to run the battery circuit right through the OEM fog light switch to the fog lights. I don't off hand know what the rating of the switch is, but I would imagine the OEM lights were 55 watts, so it should be OK. If you use another switch, just make sure it's rated at a mimimum of 15 amps. I'd also go with the 10 gauge wire, because there's more length involved.
