So I felt like I could give a try at giving back to the community. This DIY will jack some threads and steal pictures 
Mainly I'm jacking Kotori's thread with rtagn's DIY and supplementing to it.
Here's the original:
Wiring foglights for camry LE gen 6
I am graduating in december, so my pictures will go down in december when I lose the server space.. and I don't know/am too lazy to figure out how to save pics on this site; hopefully by then there will be a real thread made by a pro... but here goes:
Kit was the one bought by alfaotta. It's the only one I've tried.. ppl say the fog housing is good, but it's very hard for me to recommend this kit considering the amount of work I had to put in to it. And the biggest minus is that the switch simply isn't gonna fit.
I believe my way of install is the least intrusive way of installing this particular set of fogs, which is why I'm posting.
Step1) Remove 2x rain shields and install the fog lights themselves
As with Rtagn's guide, "Those tabs should be underneath and tucked in that piece not outside"
step2) Prepare the wiring
Mine's like this set. only the two fog light connectors (h11) look different on my kit. The red wire with the gray connector was the pos for the switch and the white wire w/ brown connector was the pos for foglight-power.
step3) Extend wires
This is where things get interesting. You'll need to extend 3 wires. As you'll notice, the switch has a yellow, two reds, and a black. If you trace the two reds far enough, you'll see that they were a single red split in to two. I extended the red, black and yellow of course. You'll count four wires here. Rtagn helped me pull the first two and I pulled two others before realizing I only needed one more.
step4) pull wires through firewall
That's the best pic I could get of the firewall.. sorry guys
If you imagine a black donut that's put in a circular box, the typical wires go through the middle of the donut. rtagn helped me pull through the outside of the donut
step5) find your switch-wiring route
There's the other side of the firewall (driver's feet)
brake-side picture
A little higher up so you can get a better picture. You can see the thick black wire above my four reds. I just followed that wire's path behind the metal stuff
Keep tracing and u get to emergency brake side.
Here's the hardest part of the install: Wiring it through that hole w/o pulling anything apart. It took me about 10-15 mins of poking wires and sticking my fingers through the fog switch hole to get the wire. So all-in-all it took me about 30 mins of thinking to find my route of wiring through engine bay, firewall, and to the switch area so that I wouldn't have to pull stuff apart.
step6) Wire it up however you please
Here's a picture of my switch wired to the low beam. This DOES NOT prevent fogs from staying on when u high beam. Wiring switch to low beam does this:
1) low beam on, switch on = fog lights on
2) low beam off = fog lights off (doesn't matter switch position)
This prevents fogs from being on when u lock up the car.
The Switch ground is kinda hidden there. It's the black wire I've highlighted
that's a pic taken from under the car. I wired the fogs' grounding wire to what I think are the low beam grounds
I was very dissatisfied with the light ouput with stock low beam h11 bulbs as well as the alfaotto bulbs, so I stuck a ddm 35watt 5000k kit in there. This light is much more satisfying but it would be very inconsiderate of me to leave it like this. TALK ABOUT GLARE. It doesn't look like much, but I have a feeling it'll bother other drivers, so I'll wait till night time to find a better spot to adjust the glare.
How am I gonna do this? the same way I did my low beam squirrel spotters back when I used the ddm kit: I'm gonna find the points of glare and spray some paint over it ghetto style
Only.. it looked horrendous on the low beams so I'll paint those spots blue instead of white.
Headlights are fx-rs done by pawel. I split the high beam with drl so I have quad highs. While I don't care for quad highs, I do care that I have the drl/parking lights. That way when I'm parked at a hilly light, I swap to parking lights to avoid blinding the ppl on the other side.
