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 interior trim panels in 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.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-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 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.

I was disappointed at first!! I had previously ordered light kit before. This set up was different.. but it ended up being better…. I didn’t have to run a positive wire clear to the the battery for this set up which was nice! Definitely recommend getting this etrailer kit for Amy vehicle

Seems very solid and installation took about an hour. Did have to cut a small portion of the heat shield away but that was pretty easy. Although easier with two people I did it by myself so it can be done by yourself. 2016 Hyundai Elantra Sport. I added a Curt bracket for the 4 pin harness for a cleanerlook.

information from staff, she knew exactly what I need to order. If I need a hitch for any vehicle I'm buying from etrailer.com

I received the hitch in good time; the directions were clear; it was easy to install. All the electrical connections have been checked and functioned as intended.

2014 Hyundai Elantra

Very easy to install. I had some trouble getting it to work at first. I screwed the ground wire to a nut in the trunk that was a ground but not a very good one. This caused some weird light problems that didn't make sense.
Once I switched to the self tapping sheet metal screw provided for the ground wire the problems disappeared. Total install time was less than an hour.

Its been a year and it still works perfectly.

I haven't had a chance to install this yet. Question: There are two tee connectors, one with the yellow wire, and other with no yellow wire. The directions say to plug in the tee with the yellow wire. What is the other tee for or where does it go? Otherwise installation will be very simple. The Curt hitch also was an easy install - your directions were great. It appears to be a very substantial hitch. Your service was outstanding. Thank you. Dave

The yellow T goes behind the driver tail light and picks up the left turn and running light signal. The green T goes behind the passenger tail light and picks up right turn and the brake light signal. See step 5 in the instructions.



by:

Installation on this wiring harness could not have been any easier. The excellent instructions and video from eTrailer hooked me right up. I was a little hesitant about how it would work since it comes out the trunk when in use. It fits nicely and I have not experienced any issues. I highly recommend this type of wiring harness and eTrailer.

I recently purchased a Draw-Tite Sportframe Trailer Hitch Receiver with the plug and play harness. The quality of my product was great and the installation process was very easy. The entire installation took less then 30 minutes and I’m very happy with the results. Thank you again!

Great Product and Great Service.

This
products is much better than other vehicle wiring harness for trailers. Much easier to install without routing hot wire to battery. I wish I would have purchased this one first.

2014 Elantra hitch, installed perfectly. Was WAY easier then the instructions stated. Besides cutting the beauty cover (plastic), the whole install only took about an hour and fit PERFECTLY. Great product.

Easy accurate on line description. Checked other sites and etrailer offered the best overall price - product and shipping. EASY installation and fit perfectly. I've experienced no problems

I have a 2014 Hyundai Elantra SE, and this set fits perfectly. This installed so easily! This was way quicker and easier than installing the hitch even which is easy of course. Overall, it was a fast and easy installation. I recommend this product.

Was very easy to plugin and get setup. Wires had good length to them, not too short, but not a crazy amount of excess to deal with either. Installation was easy.

2012 Hyundai Elantra

I just installed this and am very happy with it so far. The instructions were simple and clear, and matched up exactly with my car. Everything needed was included, and it was very easy. Since there are no wires to cut/splice it is hard to make any mistakes and it worked on the first try.



by:
2015 Hyundai Elantra

Easiest piece of assembly. Directions were clear to follow. Took approximately 10 minutes from start to finish which includes tucking the wires under the felt.

Not only are they awesome my second time purchasing as I bought a new car and needed a new hitch bar I highly recommended you guys to people on Reddit home improvement sub! A lot a people didn’t realize how easy it is to install a hitch onto a car and pull a tag along trailer for east home improvement stuff pick ups. So many were thinking they’d need to purchase a truck just to haul things. I recommended your site because if it’s easy to use ordering and videos to watch the simple installs. Thank you for your company and it’s great service!

Installation was easy and took no more than 30 min, and I had my 9 year old helping me.

  • Trailer Wiring Recommendation for a 2014 Hyundai Elantra Sedan
    Sorry to hear about the bad luck you had with the Curt Harnesses on your 2014 Hyundai Elantra. I suggest a universal kit, the ZCI Circuit Protected Wiring Harness # 119250KIT as a fit for your vehicle so it would be your best option. We tend to have better luck with the Tekonsha wiring harnesses. I attached install instructions for this harness for you to check out.

  • Trailer Hitch Recommendation for 2015 Hyundai Elantra
    For towing a small trailer with your 2015 Hyundai Elantra you would want the Draw Tite hitch # 24902. This has a 2,000 lb trailer weight capacity and would work well. For a ball mount you would need part # 3594 and for hitch balls you would need # 19258 for a 2 inch ball and part # 19256 for a 1-7/8 inch ball. For trailer wiring you would want the part # C56126 which is also a confirmed fit.

  • Trailer Wiring Harness Recommendation for 2012 Hyundai Elantra
    Yes, the Curt Custom Fit Vehicle Wiring # C56126 that you referenced will work as a plug and play wiring harness for your 2012 Hyundai Elantra. It should not affect your warranty either, there is actually a Federal Law called the Magnusson-Moss Warranty Act. The Act states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle actually caused the prob­lem in question....

    The trailer hitches we offer for your vehicle are Class l hitches with a 1-1/4 inch receiver opening and are all rated with a 200 lb maximum tongue weight and 2,000 lb maximum towing capacity. I was unable to find information about the towing capacity for your 2013 Hyundai Elantra Sedan. You will want to check your owners manual and or with your dealership to find out what the capacities are for your vehicle.

    All of the hitches you referenced are basically the same hitch just made by different companies, any of them would work very well for you.

  • Trailer Hitch Receiver Recommendation for 2014 Hyundai Elantra Sedan
    When it comes to a trailer hitch receiver for your 2014 Hyundai Elantra, I recommend going with the Draw-Tite Sportframe, # 24902. This hitch offers a 2,000 lb towing capacity and 200 lbs of tongue weight. One of the perks of the Draw-Tite hitch is that a support strap, like part # 18050, is NOT required on non-trailer loads in order to maintain your warranty. If you plan on doing any towing with your Elantra, I recommend that you start by checking your owner's manual to determine it's...

  • Recommended Hitch, Wiring and Related Towing Components for 2011 Hyundai Elantra
    You are correct - Tow Ready wiring harness # 118473 does NOT require you to run a 12V power wire up to the battery when installed in a Touring edition of the 2011 Hyundai Elantra. If you have the sedan then the harness you need is part # C56126 which also does NOT require you to run a power wire. With ball mount # 3594 you can use 1-7/8-inch hitch ball # 19256 or 2-inch ball # 19258. These are the recommended hitch balls for use with this ball mount. Hitch # 24902 from Draw-Tite will...

  • Can I Tow A Trailer With A 2016 Hyundai Elantra
    Before installing a trailer hitch on your 2016 Hyundai Elantra you first have to tow according to the towing limits posted in your owner's manual. No matter the weight rating for the trailer hitch, the towing capacity of your vehicle takes precedent. According to your owners manual, trailer towing is not recommend with the 2016 Hyundai Elantra. The reason for this might be that weight of a trailer on a hitch (tongue weight) may be too heavy for the frame and rear axle on the Elantra....

  • Trailer Hitch Recommendation for a 2013 Hyundai Elantra
    The hitch I recommend for your 2013 Hyundai Elantra Sedan or Coupe is the Draw-Tite Sportframe Trailer Hitch Receiver, part # 24902. If instead you have a GT Hatchback you would need the part # 24905 as long as your model wasn't built in Korea. As long as the second digit of your VIN isn't M this would work well. The ball mount I recommend is part # 3593. This ball mount provides either a 2-1/8 inch rise or 2-3/4 inch drop, and includes the pin and clip. If you need a 1-7/8 inch ball...

  • Tail Light Converter for 2003 Horizon Motorhome with 3 Wire Tail Light System
    To tow a trailer that uses a lighting system that has the turn signal and brake lights combined on the same circuit with a vehicle that has the two circuits separated (like your motorhome), you would need a tail light converter like part # 119178KIT. The wires on the input side of the converter would tap into existing tail light wiring as follows: Green wire on converter taps into right turn circuit Yellow wire on converter taps into left turn circuit Brown wire on converter taps into...

    We do have a wiring harness for your 2014 Hyundai Elantra Coupe as the Curt T-Connector Vehicle Wiring Harness # C56126 will only fit Sedan models.
