Ok gang, here it is, the news quite a few of you have been waiting for.
If you want to install factory fogs on your '06, and maybe all 9th gen Corollas', here is all you need.
Two lamp assembly's (one right - one left ), a turn signal/headlights/foglights switch, and the fog light relay for the fuse box under the hood.
The factory already installed all the wiring, and most likely the fuse too, for you, so that part of the job is done.
Install your lights carefully so that they are secure, open the hood and pop open the fuse box. Push your relay into it's socket, and close the box.
Drop the hood.
Remove the three screws that secure the two steering column shrouds, (one upper, one lower) then disconnect the plug from the turnsignal switch.
Now depress the plastic locking clip and slide the switch up.
Push the new switch down until it locks in place, and reconnect the plug for the wiring harness.
Carefully replace the two shrouds fastening them with the three screws.
Start your car and turn your new lights on.

Kool, huh?
And so simple I can't believe it.
Now all you have to do is wait for it to get dark, so you can AIM them properly.
Total cost will run you about $300 if you get all the parts new. That is, if you get the lights from a vendor off
ebay.
The switch can be had for $125, and the relay is about $50.
Total time to install, should be less than 20 minutes. (If you are sober.)
Hey, don't tell me I don't contribute.
You're welcome.
