This instruction is for 2000 Toyota 4Runner SR5. 2WD with 6cyl.
I had noticed in the past that there are connectors for fog lights at the front above the bumper and two round cavities which have removable caps.
Having been caught in a really foggy night going on a windy road to Lake Arrowhead, I decided to finally install fog lights. It took me much longer to locate the proper wiring even with the factory electrical manual. However, it should be much easier for the reader to follow my steps. The mm sizes mentioned are for socket needed and not the actual fastener size.
After some research I was able to find the factory lights at a great savings. Dealer price $432.00 each. I got the same for $170.00 for the pair. Wow.

The supplier’s description says no hardware or bulb is provided. Only on nut and some flat washers are needed. Mine came with white bulbs.
Below is how I installed them:
After an easy removal of the caps at each side, two 10 mm cap screws are removed that fasten the lower metal bumper to the plastic light housing. The light fixture has two brackets with holes that match the location of the removed cap screws.
1-Fog lamp installed. I put some electrical grease before inserting the connector. A black tape holds the wire folded and shorter.
Just remove it to allow the connector reach farther.
An “elephant trunk” looking bracket fits in a “U” shape opening at the upper bumper.
2-A 10 mm nut (socket size) needed which is not provided with the lights to fasten the “elephant trunk” bracket. I used two flat washers with a lock washer
sandwiched in between to keep the nut from getting loose due to road vibration.
The relay was installed next, since the fuse was already in place.
Where I got the relay:

3-There is an existing 15 amp (blue) fuse and relay location under the hood at the fuse box.
The dash cover under the steering column was removed by removing the gas cap and hood release pulls. Each had two screws and the must be pushed
toward the pedals to unclip them. The clips help keep the pulls in place during installation. There are four (4) 10 mm cap screws.
4-There were several cavities which must be for switches for different model 4Runners at the cover under the steering column, so I used one of them.
There is a red and white stripe wire located at the bottom and in the middle of the connector. I clipped it, but left a small section just in case I had to reconnect it.
A new section of red wire was soldered to this wire and heat shrink applied at the solder joint. The other end had an insulated connector at the switch.
A second white wire with an insulated connector went from the new switch to a ground screw under the dash.
See above picture.
5-Wire connector which connects the wiring from under the hood fuse box to the wiring under the dash and ends up at the combo switch at the steering wheel.
It is located on the left side behind another fuse block which was removed from its bracket for easier access to connector. Wires to the fuse block can remain connected.
6-The switch fit perfectly in the existing cavity. Toyota part information: PT297-89013-SW.
Only negative point was that the black side rather that the section with the picture of the light must be pushed in for the contact to be made.
7-The final result.
The fog light can only be on with the head lamps or the running lights on. That way it cannot be left on by mistake to run the battery down.
The lights should be adjusted with the provided spring loaded screw so that the center of the light beam is about 3” below the center of the light to the ground.
Cost: Pair of fog lights on Ebay----$170.00 shipping included.
Light switch from Toyota dealer---$10.00 plus shipping.
Relay on Ebay---$12.00
Other parts like wire/shrink tube/solder/nut/washers, were in stock.
If you prefer to install a new light/turn signal switch combo. You would not need to do any splicing. However, you need to pull the air bag and the steering wheel. I could not separate the upper and lower plastic cover of the steering column. Even after the three screws were removed. Besides, the combo switch must be more costly than $10.00. I am sure.
8- There are wires in this harness that could be cut into instead of where I did my splice, but I did not try it. Green with black stripe from the running light relay and black with red with stripe from the connector in picture #5. The red with white stripe wire changes color at this connector to Black with red stripe.
The red with white stripe wire gets grounded through the contact at the steering combo switch/running light relay.
The head or running lights must be on for the relay to allow grounding.

I hope this post will be helpful to reader who likes to install the same.
