  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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 vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This 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 vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Easy and quick

Aftermarket wiring harnesses can be frustrating. I don’t enjoy mechanic work but I removed taillights and ran wire according to the instructions. After repairing a bad connection, everything worked. Then, my lights began to short out and malfunction on a trip. It turns out that the main wire going to the plug wore through and was touching metal. I ordered another identical kit but placed the wire in plastic automotive conduit before routing it underneath my vehicle. It’s been great ever since. Spend the extra time and money to do it right.



by:
2016 Hyundai Tucson

Overall not to bad, but not like in the youube video. The wires are to short on the passenger side of the car. When you plug in to wires at the tail light the wires that go to the junction box are about 18" to short. There is no way to mount the box on the frame like they show in the video. I just left it inside below the light fixture dangling, hopefully it will work over a period of time. I guess I could have spiced extensions on the wires but for what you pay for this light kit, it seems they are a little chinsey on the wire length. Plenty of green wire going over to the passenger side tail light. At least everything fit!



by:

Wiring Harness was very easy and quick to install and after a year on the vehicle there have been no issues. Product did arrive fairly quickly also. Seems to hold up well with salty conditions of our winter too



by:

Does not work correctly. I’ve been on the phone with tech support numerous times and although they agree it was installed correctly, they keep giving me new things to test. VERY frustrated and unsatisfied.

I apologize that this issue is still not resolved. I resent this to Customer Service so that they can reach back out to you.



by:

So easy to install! The wiring harnesses interfaced perfectly with the car lights for a super simple connection. Plenty of extra length to allow you to position the connectors however you needed.



by:

The wiring kit for my 2017 Hyundai Tuscon, that was very easy to install. I also ordered the hitch from here, bolted it on by myself, the whole thing didn't take long at all.



by:
2016 Hyundai Tucson

Directions were a little confusing but overall not bad. Not the easiest hookup but was on a new 2016 hyundai tuscon. I would recommend this wire harness again especially if someone has some knowledge of cars. Not for the guy who cant change his own oil or air filter, it would be too complicated.



by:

Everything was included that was needed for the install. For some reason my vehicle needs a wire that runs from the rear of the car all the way up to the positive side of the battery terminal under the hood, which makes it a separate circuit with its own fuse. By removing the lower black plastic molding under the doors the wire can be neatly tucked inside for most of the way.
works great.



by:
2016 Hyundai Tucson

This is the third trailer wiring harness I have bought from e-trailer...Installed fine and works perfect....



by:

Overall the product does what it is desgined to do however 2 tips would be the wire to the drivers side light needs to be atleast 1ft longer and you should probably mount the box to the frame the double sided tape wasn't enough. But in order to do that you need the drivers side wire to be longer otherwise its up in the body of the car. But otherwise works as planned.



by:

Simple installation!
All the connectors
fit together as intended.
It's been installed for over a year without any issues.



by:
2016 Hyundai Tucson

I got it to work... wire lengths weren’t optimal for a 2016 Tucson. The harness for the drivers side was a bit short forcing me to mount the controller in an awkward place.



by:

The directions are so easy to follow to install this wiring harness. Product is made of quality parts.



by:

Little difficulty running power wire. Wish it was a little more plug and play. However worked very well once installed



by:
2016 Hyundai Tucson

The drivers side was made way too short. The power converter black box was up inside the fender area without any way to fasten it to vehicle. On another day, I will probably end up cutting the harness and extending the wiring somewhere between 6-10 inches at least.



by:

Fit like a glove, very easy to install and looks great! Solid and made to last as long as I do. Nothing was out of line and needed no alignment for all bolts to go in. Again great hitch!



by:

Went on quick and easy. wireing harness worked out good too

  • Troubleshooting Trailer Wiring Installed on Vehicle that Prevents Blinkers from Working
    Typically the issue you are having is just the connectors of the trailer wiring harness not making a solid connection. Disconnecting them and then reconnecting them typically clears out any issues but you might check the conditions of the pin to make sure a solid connection is being made. The converter box of the harness # C56348 does not affect the wiring of the vehicle so it most likely not be the issue.

    After reviewing the notes on your order I see that you now have the correct Curt T-Connector Wiring Harness specifically fit for your 2012 Hyundai Tuscon, # C56348. The Curt T-Connector 55528 that you referenced is considered a fit for Hyundai Tuscons from 2005-2009.

  • 2016 Hyundai Tucson Trailer Hitch and Wiring Recommendation
    For your 2016 Hyundai Tucson, the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13240 is a custom fit. For the wiring harness you are seeking to go with it, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56348. This harness does route outside your hatch so you don't need to store the connector inside. I recommend using the mounting bracket # 18144 which can attach to the plastic shroud near the hitch for a very clean look.

    Trailer wiring harnesses for your 2016 Hyundai Tucson, # C56348 and # 118501, both install the same way. They connect to the vehicle in 3 places: behind each of the tail lights and to the battery.

The other Curt hitch part # C13066 that has been confirmed as a fit for your 2015 Hyudai Tucson would require the use of the strap since it is not rated for use with a weight distribution system.

  • Troubleshooting Curt Trailer Wiring Harness Installed on 2010 Hyundai Tucson
    Unless your trailer is unusually well lit, the # C56348 wiring harness should have plenty of capacity. From your description, it sounds like your converter has an internal short that is allowing the 12-volt feed from the battery feed back into the vehicle taillights. You can confirm this by using a circuit tester like part # 40376 on the inputs of the converter. With the vehicle shut off, you should only see power on the 12-volt battery feed. If you find power on any of the other wires,...

    The two 4-pole wiring harness kits offered for your 2016 Hyundai Tucson, Curt # C56348 and Tow Ready # 118501, will have an identical installation procedure, but I recommend the Curt since it saves you a few bucks and has a higher current output. This higher output simply means less chance for the trailer lights' power demands from overloading the harness and blowing the included fuse. I have linked an installation video and help article that will show you the entire installation process. If...

  • Installation of Curt Trailer Wiring Harness on 2017 Hyundai Tucson
    I've heard the driver's side wires referred to often as shorter than ideal causing mounting further into the body of the vehicle but never too short to fit. Anywhere you can secure the module is sufficient but you may need to use zip ties instead of the included tape. The manufacturer confirms the fit for all 2010-2019 Tucson models. Let me know if you need further help, and if so please include pictures of the issue for reference.

    A lighting tester that uses LEDs, like the one in your photo, will take very little power to illuminate.

  • Why Does Trailer Wiring for 2014 Hyundai Tucson Require Running Wire to Vehicle Battery
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery.
