I tried doing searches in the archived forum and this forum with no real solid answer. I'm tryiing to do a frontend conversion and need some information on hooking up the foglights. I don't need a fog relay right? since there were no foglights in the 98-00, there won't be a place to put it, correct? How is the wiring done, do most people just tap into the park light circuit?
Also, are the bulbs used in the foglights found on all major cars? i need to go grab the sockets for 9006/9005 and the fogs sometime this week. Do they sell them at autozone?

They're standard 9006/9005 bulbs. Autozone may or may not have the selection/inventory you would prefer, however.
I've seen that diagram in my searches, however, i was hoping for something that hook up to the parklight switch and not hooking it up directly to the battery.

Why? Because you don't want to install a foglight switch?
The problem with simply tapping into the parking light is that you might draw more current through that wire than the wire can handle, which will cause it to overheat and short out.
That's why the diagram shows the use of a "Bosch" automotive relay. This lets you take power through a dedicated wire to the battery, but based on a signal from another circuit.
If you want your parking lights to trigger your fog lights, then tap pin 85 to a parking light wire, rather than to the switch, as shown.
You can get a 5-pack of 30-amp Bosch relays (with pre-wired sockets) for about $10 on eBay.
I didn't want to use that diagram becuase: 1) i didn't want an extra switch that doesn't look stock and 2) tapping the park light circuit seems simpler, though i am aware of the drawbacks, i was hoping that someone figured something out that would solve that problem.
any idea if using that diagram + hooking it up to the park light switch is doable?
also, what is the difference between the fuseholder and the fusebox?
That relay will work fine. You'll need some "quick disconnect" 0.25" receivers for the blades on it though, or a pre-wired socket.
As I said, use that diagram, but the wire coming off 85 of the relay, have that tap into your parking light instead. Whatever switches on/off your parking lights will then also switch on/off your fog lights, but you'll be drawing power from a dedicated wire to the battery, rather than overloading the parking light wire.
The fusebox part of the diagram is just so that the switch gets its power from a source that's only active ("hot") while the car is on. (Implying the use of an Add-A-Line.) That way you can't accidentally leave your fog lights on... eventually leaving you with a dead battery and needing a jump start.
The fuseholder (between the battery and the relay) is to provide a fuse for the circuit powering the fog lights. Fuses break circuits before the amperage draw exceeds the capacity of the wire. Unfused circuits result in fires in your car (i.e. bad). You can get a 20-amp fuseholder with fuse at Autozone for about $7.
You also need to make sure the wire you use is sufficient gauge for the amperage draw of your fog lights. Here is a chart that shows you the relationship between gauge and amps. (Bottom right table.) For 20 amps, use at least 14 gauge cable.
where the 'fuseholder' is located, can i wire it to an empty slot in the car's fusebox? i'm not sure if there is any, i'll have to check, but is there an easy way to get this done?
ps. sorry for these really noob questions, i really really don't want to mess anything up.
There's no "spare" spaces in the fusebox in the Corolla to wire into, sorry.
The easy way is to just solder a fuseholder inline near the battery. You can get a mini-blade fuse inline holder if you prefer the consistency of that, rather than throwing an AGC fuseholder into the mix.
There's a nut on the positive terminal wire of the battery that's meant for adding ring terminals to. (On boats and trucks, that nut is often a wingnut so you can change wires by hand.)
If you are after the ultimate factory grade install, read on.
This is what I am running now and have spread an account of my install on multiple threads. This oughta encourage you because this is doable.

There is. If you have the right pins on hand and know where to tap. To get those pins, go to the salvage yard and pull a number of electrical connectors from Toyota cars, specifically, the plugs. The female pins you are looking for are approximately 2.3mm wide. Take a 1mm flat screwdriver to pry up the pin lock on the plug, then use same screwdriver to carefully lift up the lance within each pin, and pull the wire out.
So there is a 15A fused fog circuit in the instrument panel junction block (behind the coin drawer). The entire circuit is downstream of the taillight system, but each fog light draws only 4.8A or something so there's enough left for your tail lights.
As you can see the fuse covers two pins. One goes to the switch and "pin 85", and one goes to "pin 87" of the relay.
For the ultimate factory look, get the turn signal stalk with fog switch, which I also have installed. The contacts on that thing are pins 10 and 11. The screwdriver above helps because you will be replacing the turn signal stalk and add two wires to the original turn signal stalk plug, this time one of the two is 1.3mm wide. Good luck finding a plug with that.
Not intimidated? Good luck.
BTW our gen 8 sticky touched on this subject.

LOL, that seems much much much more complicated than even a frontend swap. It's a project onto itself .
where would be a good place to mount that relay? near the front, towards the lamps or near the back?
I'm itching to start this project but can't make up my mind whether i should do the foglight wiring now or later.
currently on my plate:
fix bumper i bought for $10
front end conversion (i have all the parts already, except the 9006/9005/fog sockets)
sand, bondo, and paint the car (just got the air gun yesterday)
install tein h-techs and strut bar (sitting in garage)
