Alternate (neater) version of Fog light wiring mod...
<center><img src="http://pictureposter.audiworld.com/47880/fog_light_mod.jpg"></center><p>
First, a big thank-you to Richard Solomon for his writeup of the fog light wiring mod (https://www.audiworld.com/tech/elec43.shtml).
I did the mod this weekend, but in a slightly different (I think, neater) way...
I found that there is no connector inside the fuse box on the "load" (right hand) side of the fuse at position 27 - even though there IS a connector at the "live" side and a fuse in that position! So I replaced the fuse with a 15A and just used a radioshack fuse tap (shortened & soldered) to run a wire from the load side of the fuse. Then on the other end of the wire I just soldered a small 3/16 spade connector and inserted it into the "load" side of 36 without any fuse in place (I blocked off the "live" side of 36 using an old fuse cut in half). All you see is one short wire and the fuse in pos 26 is now used for the fogs. Much nicer looking IMHO...
If you don't have the small spade, you can take a spare fuse, cut it in half, use half to block the live side of 36 and break apart the other half to use as the spade (you obviously need to be able to solder to do this). Make sure you heat-shrink everything to insulate any exposed bare metal!
This was so quick and easy, I wish I'd done it months ago.

Do it my way, for no wires on the fuse side of the box...
it's a little more PITA though, you gotta take stuff apart, cut and splice etc. <a href="http://www.kris-hansen.com/audi/fogmod.htm">Click.</a>

Ouchhh! Why didn't you just...
... connect the #36 feed wire (w/butt connector, 2nd photo) direct to the high current source (red wire, 2nd photo)? This avoids the need for the relay as the fogs can't be switched-on unless the side-lights are on anyway. (Sorry, I know it's a bit late now!)
Better still would be to connect the red wire to the ignition-switched feed (yellow stickered nut just to left of your red wire, 2nd photo) to avoid the possibility of the fogs being left on when you leave the car.

Well, first, I wasn't sure how much current the fogs/fog relay would consume..
and Audi wiring being Audi wiring, I didn't want to chance it being more than the little parking light wires could supply happily. Second, I had already committed to using the relay when I realized that I could have just as easily used ignition switched (which was about the same time I realized that you couldn't use the fogs with the lights off due to the switch, which is why I wanted to use the parking lights as the trigger.. I was thinking back to the day when the fogs had their own switch..)
Maybe I'll re-do it, to simplify the process for others.
