Quickly and easily install a 4-way trailer connector on your Hyundai Tucson with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.
This custom-fit T-One connector plugs into your Hyundai Tucson's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove some interior trim and the tail light assemblies to access this harness.
Once installation is complete, the 4-way flat connector will be stowed in the spare tire compartment of your rear cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
Circuit-Protected Tail Light Converter
A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your Hyundai Tucson's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your Hyundai Tucson operate.
This converter safeguards itself and your Hyundai Tucson against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your Hyundai Tucson will remain feedback-free.

This is the second time I have purchased from e-trailer and they provide a wonderful service before and after the sale. The ordering is very easy on their site due to the great search engine for finding the correct items for an individual vehicle. As for the products- well installing the wiring harness too me about 45 minutes and most of that time was spent in removing/re-installing the trim panels and tail lit assemblies. As a computer professional I only wish some of the software could be as much "plug&play as these wiring harnesses are. Every this is provided in the package and instructions are very clear and concise. I recommend e-trailer and the T-One wiring harness to everyone needing to do a new install. 100659

The harness itself was easy enough to connect. The operation was hindered by the poor resolution of the pictures on the instruction sheet in the box–the .pdf file available online is a much better source. (http://www.etrailer.com/instructions.aspx?pn=118397) The directions for loosening the tail lights and (especially) the interior panels lacked detail. Anyone who is not familiar with the fastening (and unfastening) of the lights and panels is prone to damaging them. There is only one picture illustrating the loosening of side panels, and it shows only the most trivial action. I’ve included here the procedure that I worked out. (There may easily be a better method–and it would be a wonderful thing if etrailer would document this operation in a video.) To start, the motion to remove the tail light is a slide straight out to the side, anything more than a very gentle pull means you're going in the wrong direction–there is no twist or turn when removing the light assembly. There are two, plastic alignment pins that are part of the tail light assembly. They sit on the outside edge of the back of the light assembly and point straight in toward the truck interior. Take a careful look at picture "D" in the online .pdf. It does look as if part of the motion is a pull or turning motion to the rear, but there is no rearward or turning motion. The instructions for the interior panels simply say "be careful not to damage clips" without any directions on how one is supposed to manage that, yet getting these things loose or off without breaking them is key to the operation. The threshold plate, once the two screws are removed, must be gently worked up--there are insertion-type fasteners clipped on the bottom which will free if one starts from one end, prying only an eighth of an inch or so and working along the whole length, and then repeating the operation until the unit comes completely free. A thin plastic spatula or a wood shim work should well for this. The side panels are more complex. The fasteners will break and the whole panel can be cracked if too much force is applied. Carefully examine picture “G of the online .pdf. Note how far away the panel must be pulled to do the installation. There must be room for hands and a drill on the passenger side. The driver side need not be opened so extremely–only a hand is required. This means that several clips of two different varieties must be unfastened, especially on the passenger side. At the upper left of picture “G,” the two different “clips” can just be made out. At the very top is a plastic tongue or tenon with a catch at the bottom of the outer end. There are several of these tongues along the inside, top edge of the panel, each about 8-12 inches from the last. Below the tongue in the picture can be seen the tip of a white insert. This insert came from the hole in the body panel that is visible in the upper, center right of the picture. There are three of these white inserts, and they are themselves held by fragile mounting sockets on the back of the panel. The socket is not visible in the picture, being just hidden by the lip of the panel. The insert’s panel socket does open to the bottom, and the white insert’s head slides in and out of the socket from the bottom. The proper motion to loosen the panel seems to be a gentle push up and slight pull out–perhaps no more than a quarter inch outward. The pull up has to be a half-inch or so, and this requires that the quarter-inch pull out clear a lip where this lower panel meets the next panel from above. The white inserts may stay in their holes, sliding out from their panel sockets, or they may stay in the panel socket, coming out of the hole, either is ok at the moment. They key is that the upward motion directs the pressure toward the open bottom of the panel sockets, and at the same time, the motion helps to lift the first tongue on the upper edge past its catch. It might also be possible to slip a small screw driver behind the panel to push and lever against the inserts to get them out. I didn’t try that, and you’d need to be careful to not scratch the paint. A shim might also work for this. I’d start from the bottom and work up if I tried this technique. It’s worth a try, especially if the pull up and out isn’t doing it for you. Once the panel is free enough, work your hand in behind the top of the panel, locate the end of the next tongue’s clip protruding inside the receiving sockets and push the tongue up and out.. You’ll need to do at least two of these on the passenger side. Three is certainly better if you can get your fingers back that far–but that was farther than I could squeeze. In retrospect, I might have been able to reach that third one with something thin, perhaps a screwdriver, to push it up and out. Follow the directions on the sheet for hooking up the wiring. Examine the T-connectors on the harness before trying to disconnect the ones on the vehicle, and maybe do a sample plug and unplug there–they disconnect easily if one is doing the right thing (an easy push in on the small retaining lever on the side)–and break easily of one does it wrong. Don’t pull on the wires, ever. Be very careful at the point where you must drill a hole behind the passenger side panel to attach the grommet. It is all to easy at that point to pull the panel too far away and crack the plastic. If the installation did not require drilling a hole behind the passenger panel, it would be much safer and easier operation. Also beware of dropping the screw to hold the grommet–there are places nearby and below where a screw can disappear forever. When reattaching the side panels, the simplest method seems to be to have the white-plastic inserts in the panel sockets–not in their holes on the truck body. This allows you to guide the panel into place, directing the tongues and inserts into their receiving sockets and holes. The harness wires from the driver side must run across the spare tire compartment to the passenger side. Rightly or wrongly, I routed them beneath the plastic threshold so that they would not dangle.24542

This,by far,was the easiest time I've ever had wiring a vehicle for a trailer.The harness for a 2005 Hyundai Tucson fit perfectly-no worries about anything not fitting,or not enough wire to reach both sides.I was finished in about 20 minutes and was honestly stunned. The harness arrived faster than I thought it would,and was well pack- aged.Thanks for the great service,and I am extremely happy with the product.79504

This wiring harness makes hooking up wiring a breeze. I had it done in no time. I would highly stress being careful removing the tail lights. There are a couple of clips that are super thin and easy to break. 76963

Very professionally made ideal would recommend all people to use the proper product for the job not those cheap universal types that create havoc and have a high casulty rate to your out of pocket cost. This is the most effecient proper cost way to go.58443

If you can follow instructions, and have a little bit of patience and understanding, then you will have no problems putting this harness in. Took me just around 1 hour, and that includes cleaning everything that I removed. Instruction were good and accurate. Will buy all my trailer wire harness's from etrailer.com from here out!40600
I was hesitant about buying this harness as I thought it was a little pricey, and figured I could splice the wires myself. Not to mention I wasn't sure how well it would "ACTUALLY" fit with the factory wiring. It could not have been a more perfect fit. Wires were plenty long enough, all connectors fit perfectly, wire seems to be a good gauge for the application. Installation took me about 20 minutes from start to finish. It was a breeze. I would buy this product again and recommend it to anyone. Thank you etrailer.... well done!30329
Good instructions and it worked just fine! Like that entire harness is inside the vehicle and won't get wet when not in use. Only issue is that to connect to trailer, I have to close the cargo door on the 4-wire cable. I don't want to sharply bend the cable. Must be a better way.24061
SOooo easy to install, clean So quick, harder to read the instructions than do the job. Took about 35 minutes. This is the only way to go. I've installed brand X, which is cheaper, but always end up trying to figure out which wires to spice into and always end up doing it wrong the first time. Brand X is always a 3 hour or more job. This system is so slick, nothing to mess up and worked right first time. This "T" connector system is terrific.2067
