Ok so here it goes guy full write up step by step on installing fog lights on a 98-00 corolla with oem fog stalk.
Things you will need:
#1 oem fog stalk, got mine on the junkyard off a 98 avalon for $9 i got the relay for free as well
#1 fog relay
#2 oem fog plug(you decide from which car you want it from at the junkyard) i got mine of a 01 corolla cause i had already ordered my fog lights so i knew what plugs i needed to take.
Also need plenty of wires you decide what colors you want as long as you remember where you going to put them at.
#1 roll of black tape(electric tape) or heat shrink extenders(i used both to be sure)
#1 oem fog stalk connector(when you take the fog stalk from whichever car take the plug thats connected with it) i grabbed mine from the 01 corolla i mentioned earlier.
Ok now lets get to business. First you want to take off the steering column cover, its held by 3 screws, 1 in the bottom of the steering column and 2 behind the steering wheel. Turn on the car to turn the steering wheel and be able to take off the screws. I got no pictures for that cause at the time i forgot to take one but im pretty sure someone here as posted a thread on how to locate the screws. Next you want to take off the 2 screws thats holding the turn signal stalk in place, there is 1 screw on top and 1 on the bottom. Once the screws are off slide the turn signal stalk out and unplug the connector. Now you cut off your old turn signal connector and wire the new one making sure each wire is wired with its same color:

Once you wire the connector you should 3 wires left that does not goes with the rest of the wiring to the car. (These are your fog switch wires on the new oem fog stalk your going to put in) In my case the 3 wires color are 2-red greens and 1 red blue. Now what you want to do is wire the red blue wire with one of the red green wire together. This gives continuity to the other red green wire. Now take the fog relay and face it up with the pins towards you and the small pins facing your right side

Now grab some of the wires you grabbed from the junkyard or had cause your basically doing your own wiring harness, now 98-00 corollas didnt come prewired but they atleast gave us the 15amp fog fuse which comes pretty damn handy if you want your fog lights oem like mine lol
Your going to take a wire and put it on one pin of the fog fuse and plug the fuse back in, next your going to splice the end of the wire into 2 wires, once thats done your going to plug them on the 2 pins that is on the far side of the relay,

you could extend these wires from your fog fuse or cut them short, me i personally cut them short and kept it by the fuse block since we dont have a fog relay socket like the 01+ corollas, now your going to grab another wire and wire it to the red green wire thats is the last wire left on the oem fog stalk connector to wire, then run that wire to the SMALL pin infront of you that is facing right by doing this you are now in control of your fog lights and have wired them independently. Now the last pin on the relay is the big pin infront of you, grab a wire and run it to your fog light, this wire is your 12v wire going to th fog lights from the relay. All thats left is grounding your fog lights, the black wire from the fog lights is for ground you can ground them wherever you want. Now plug in the oem fog stalk and test the switch before reassembling everything, this is where i have my relay fuse and some pictures of how everything came out and the end results

I made 2 hole on the relay housing and zip tied it to a hole that was not disturbing anywhere
This is how it looks after i put everything back
