I may be one of few who have done this. I read over the other fog DIYs and found that they all suck. So here's a good one. This is a way to avoid all the headaches of installing fogs.
The other guy's DIY has you wire through the firewall, hack into your fuse box, and install a cheap looking switch. That's just a pain in the butt to do. My way: Wire the fogs in a way that you can use the headlight twist switch control them. No crossing the firewall, no hacking the fuse box, none of that junk.
Okay here's what you need. (This is a wiring diy, not a full install. you have to use another diy to get the fogs to fit in your bumper. I'm not responsible if you screw something up, but I'll be glad to help you figure it out.)

Here's what we're doing...
Your light switch has three settings: off, parking lights, and headlights on.

What we're doing is to wire the fogs in with your running lights.
when the switch is in the "parking lights" position, it will look like this

When the switch is in the "headlights on" position, it will look like this:

And of course, when the switch is off, all of your lights will be off.
How to do it:
1) use the other guy's DIY to install your fogs *eBay fogs work great, K2 fogs are basically the same. either way, you're getting about the same quality. Don't spend more than about $50 for fogs.*
2) Once you have your fogs in, its time to deal with that huge wiring harness, switch, fuse, and relay... That stuff is all junk. All we need is the wire. You don't want that cheap switch in your car anyway. The wiring should have a long wire that goes out to your left fog light, and on the right side, it has the power wires that come out of it. Go ahead and plug in the fogs to the wiring.
3) With our simple knowledge of light bulbs and electronics, we know that there is a power and a ground wire going to each fog light. you can use a knife to cut the wrap that's covering the wires in a couple places. Don't cut it all off, but just check in a couple places to make sure which wires are where. I believe it's a black and a white wire going to each fog.
4) once the wires from the fogs combine into one strand, they should be wired together into a single set of + and - wires. leave as much free wire as you can, but you can cut off the rest of the crap (fuse/relay/switch)
*cliffs so far: we're simplifying the wiring down to the +/- wires from each fog, and the +/- wires that will run the power to them.
5) strip the ends of the wires
6) we're going to need to ground the - wire, so we find a wire connector that is a ring, or a Y like the ones shown.

We connect (crimp) it with pliers to the wire. make sure its on tight.
7) connect the ground wire to the frame. I connected it to the radiator support, just pull out a bolt that connects to the frame, stick the wire connector under it, and tighten it back down securely.
8) Time for the good stuff. Run the + (power) wire up behind the headlight.
9) unplug the parking light on the side where your fog wires are run. (passenger side if you've followed my directions) notice the two wires coming our of the plug. The red one is the one we need. -you may have to cut back the cover a little bit.
10) use a splice connector

to connect your fogs power wire into the parking lights power.

That's pretty much it! Here's a wiring diagram I drew up. It's not too hard. let me know if you have any questions. Thanks

No problem man, good luck. I love mine.
