The Hyundai Santa Fe comes with two side markers. The purpose of side markers is to enable a driver to see another vehicle that is approaching at an angle at night or at a stand still and to see it early enough that the other driver can stop in time to prevent a collision or at least slow down to reduce the severity of the collision. The addition of side markers in vehicles was started in Jan of 1968 and has since been in every vehicle on the road. Unfortunately some of these markers are just that, markers. Some automakers have incorporated making them signal lamps as well. The Hyundai Santa Fe has inboard mounted signal markers in the combination lamp, which are not visible from the side. The vehicle has side markers but are the type that are just static and do not signal.  Side markers that signal give the added security that any pedestrian or other vehicle on your side will realize your intention of turning. This reduces your chances of getting into an accident. For these reasons, I decided to modify the current markers into signal ones. The location of the markers on the Santa Fe depends on the model and or location where purchased. In the USA they are on the front side fenders. In Europe, they are placed up near the metal close to the mirrors. Regardless of location this modification will convert these static non directional signal markers into fully functional signal markers.

After you remove the combination lamp you will see the side marker from the opening. This opening is where you will be able to fish the wires later on. (See pic 03).

Place the combination lamp housing in a comfortable area to work with. Turn the housing so that the big round knob is to your right. This will allow you to see the peg holder that holds the lead (pigtail) wire connector to the housing. (See pic 04 A) You need to take out the connector in order to have ample room to work with it. (See pic 04 B).

I used a hex screw to push in the hole to pull the connector out. You may find something else that is better. Once you dislodged it put it to the side to work on it later.

The side marker is attached to the fender by one screw and a hook. (See pic 05 A) Unscrew the screw and push the marker gently towards the rear of the vehicle then towards you.
Once the marker is out you will notice the hook. (See pic 05 B).

Once the marker is detached from the fender, detach the marker light from the side marker housing. Set the housing to the side.

Note: My left marker came out without any problems; the right one was another story. It refused to unscrew. At this point I had to take my dremel tool and cut the screw from the inside to be able to take it out. Use your better judgment if a situation like that comes up.

The side marker has two color coordinated wires. Depending on which one you are working on, the color is different. The left marker has one black and one pink wire. The right marker has one black and one pink w/ black stripe wire. These wires are covered in a wire loom that is also wrapped in electrical tape. (See pic 06 A) Take off the electrical tape. The wire loom will then be exposed. This loom is cut open on one side; carefully take out the wires out of the loom.

As you can see there is not that much room to work with. At this point you will need to cut the Black wire only. Make sure you leave enough room to be able to work on both ends of the cut section. I chose to cut it at the halfway point. (See pic 06 B) Leave the other wire alone.

Picture # 7 shows you the cut black wire. The pink one is left alone.

Both the side marker and the combination lamp have color-coordinated wires. These colors are outlined in the 2002 Hyundai ETM (Electrical Troubleshooting Manual). But the colors of the wires that consist of the lead (pigtail) wires (mentioned in step 1 above) are not in the ETM. The following diagram shows the original and new connections along with the colors of the pigtail wires. The original diagram can be located at https://dcsonline.hyundaidealer.com/customer/tech_info/tech_sevice_main.html

Note: The new yellow wire looks red in the photo.

Take the lead (pigtail) wire harness and take out the rubber cover of the wires. I used an utility knife.

You may want to remove the light to prevent damage to it. (See pic 09 A)

Once you have the rubber cover off you will have better access to the three wires of the lead (pigtail) wire harness. (See pic 09 B)

At this point you should reconnect the wiring harnesses to the combination lamp.
Reconnect the negative battery cable and insert your ignition key and test the lights.
They should at this point work and perform the following functions.
