I don't know if anyone is still interested in doing this but I am currently in the process of putting fog lights on my car. I am not 100% sure that it will work. I am trusting some of the people on here that I have used as research. I have talked to mechanics at my dealership that said either it can't be done or would be ridiculously expensive. I have read posts where guys wired directly to the low beams with relays or inline fuses, there were lots of warning and seemed dangerous with no one clear answer. I have read through this entire thread and decided to try to go as factory as I can based on dxtra196's experience.
Here is what I bought:
Two Factory Fog Lights from Ebay for $300 total
One factory harness from a Hyundai dealer $150. Part Number 91840B1040. The one on ebay is a little cheaper but I read that it wasn't wired properly require soldering and seemed like a hassle not worth the couple of extra bucks. For a few more dollars I got the real deal and it shipped a lot quicker. No muss no fuss.
I bought the stalk from ebay because dxtra196 said it worked with no problems so I am taking a leap of faith. Total $180 with shipping.
I have not done this part yet since I don't have the part so I don't know if this will work or not. Again leap of faith. I will update once I have the part installed.
I have seen a lot of incomplete instructions or instructions that weren't dumbed down enough for me. So for those of you that are still interested in doing this here is my take on it. I took some pictures but for the most part it should be pretty self explanatory if you have the parts in front of you and take some time to look at your car with these instructions to follow along.
Remove top cover there are plastic rivets. You push the center in gently and then you can pull out the rivet by hand. Find 13 plastic rivets push down pin in the middle then pry up set aside and remove top cover. Once you remove the cover you will see that the bumper is still connected to the frame. To disconnect top of bumper from the frame use a 10mm wrench to remove 4 bolts. On each
wheel well there are one normal screw and 4-5 plastic screw/rivets. Use a phillips head to remove these. I needed to turn the tires to get good access to each side. Underneath you will find more of the plastic screw/rivets. Some of mine were missing but I would say there are about six total.
The next thing to remove is the headlight washer covers. You can pull these out and then hold the extending part to get a better hold of the cover. Gently rock the cover side to side and it will slide off (some fluid will come out when you are messing with them). I took a picture.
The final thing to do is to disconnect the sensor harness from the car. You should be able to pull the bumper back enough to see the connector. It is on the drivers side of the car. It has a grey lever/cover on it. Just raise the lever and the connection will release and you can pull it out.
Once these are all off you can take the bumper off. Start from one side and work you way towards the center. It is tight under the headlights but don't be scared to use a little force. I used a small screwdriver to help pry it off.
Now that you have the bumper off you will see how the existing harness is connected to the bumper and the parking sensors. You will also see the blanks that are attached to the bumper where the fog lights are suppose to go. Starting with the blanks use a 7mm socket or wrench to remove the 5 screws holding them in place. You will need a socket with and extension to put them back when you attach the fog lights to the bumper.
After you have both fog lights on take the new harness and lay it over the existing one mirroring the layout. Remove the grey harness rivets where they are attached to the "styrofoam". There are two of these at each end of the bumper. Be gentle with these or you will break the plastic they are in like I did. Luckily I was able to drill new holes for the new harness.
The connections to the sensors are pretty easy to take off. Basically a push lever to release the harness from the sensor. There are a few that are tough because the lever is on the bumper side. Use a small screwdriver or crescent wrench to press the lever and grab the connector to pull them off. Once the old harness is off, starting from one side start putting in the rivets and making connections. After they are all done and the harness is secure you can put the bumper back on. Push it back into place under he headlights so it is secure. Reach under the drivers side of the bumper and connect the harness to the car by securing the connector and locking it in place with the grey lever.
Pull out the headlight washers and put the covers back on. They have to be all the way on so that when they go back into the car they are flush against the bumper. If there is any gap pull them out again and keep rocking the cover onto the washer until is rests flush (some fluid will come out when you are messing with them). You will hear small snapping noises, that is just the cover seating itself.
Now put all the screws/rivets back in place to hold the bummer and splash guards. Don't forget to put the bolts on first before you put the engine cover back on.
I will update this post once I get the stalk and use dxtra196's instructions. I will take photos then as well.
