Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.

    • 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: 5 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 installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

We bought a trailer hitch and wiring kit for our Haundi Tucsan and it is wonderful. built well, very sturdy. Easy install. We use it all of the time either with a little trailer or our bike racks. Good product and a fair price.

Lots of frustration involved in getting this to work properly. Trailer turn signals/brake lights/emergency flashers worked very intermittently. One side or the other would work or not at all, rarely did both sides work at the same time. Parking lights worked fine. All of the trailer lights worked fine when connected to another vehicle. Long story shortened - I ended up replacing trailer turn/brake/flasher bulbs (1157) with LED bulbs and the problem was resolved. Note that the vehicle lights worked properly during the trouble shooting.

The wiring harness was very easy to install. I did however use 10 or 12 extra cable ties to make sure it was secured well especially up above the exhaust tips.

The directions were clear, and easy to understand when it came to outlining which holes under each tail light you were supposed to snake the wires through that was a big help.

The pricing was rock bottom, and the harness appear to very high quality..I will definitely purchase any other trailer or towing products I need from Etrailer.com

The harness itself is great. All the parts were there and everything works so far. The issue is the attention to detail with the directions. This is installed on a 2007 Tuscan. The directions are not bad, just not detailed enough for a good installation. First, there are three screws to remove for the lights, not two. Second, it is not easy at all to "feed the wire up through the bumper". You need a stick or string to slide down through, tie or tape the wires to it, then pull it through the bumper. Third, there is nothing showing you how to keep it safe from melting on the exhaust pipes for both sides. I am a professional handyman, so it was not difficult for me to take care of the issues. I just think it needs more details to help others. Again, everything works fine, the wires are solid, and I would buy again for other vehicles.

I recently purchased this hitch and related wiring accessories from etrailer for my 05 Hyundai Tucson. Following the included installation instructions I found the hitch easy to install. Total install time including the wiring adapter was approximately 1.5 hours without rushing.

Everything worked out great on my trailer hitch kit. The item and wiring harness were well priced ($50 less than next best competitor) and accurately described and fit/installed easily with all necessary parts. Definitely will keep them in mind for future orders!



by:

The kit was easy to install, but has been giving issues with turn signals blinking real fast or sometimes not at all. I swapped out the bulbs in the trailer for LEDs which pull less current and that has seemed to fix the issue.

Works great. we had ordered the plug for our application and did not have enough time to return or reorder. but with snap splices made it work. Still ease to install. Works great. Great service.

Everything was as promised. My wife and I installed in less than an hour. Pretty good for a 69 year old! Adam E. is a great sales/service representative.

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Troubleshooting No Turn or Brake Signals On Trailer Wiring
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # 3808 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean and...

  • Trailer Wiring Harness for a 2007 Hyundai Tucson
    On some vehicles the specific trim level might matter. But in this case, for your 2007 Hyundai Tucson and a trailer wiring harness, it does not matter. You can use Curt harness # C55528 no matter what trim level you have. I have included a link to the installation instructions for you to view.

  • Recommended Trailer Hitch Receiver and Ball Mount for Rise Needed Without Bumper Fascia Contact
    For your 2005 Hyundai Tucson, I recommend the Curt Trailer Hitch Receiver # 13526. This will have a 12-1/4 inch measurement to the inside top of the receiver opening and from the hitch pin hole to the outer most part of the bumper will be 5-3/4 inches. For your ball mount, I recommend the MaxxTow Adjustable-Height Ball Mount # MT70068 to give you the bumper clearance and then recommend hitch ball # 63845 for a 2 inch ball or # 63847 for a 2-5/16 inch ball. Then use # e98880 for keyed...

  • Troubleshooting Intermittent Turn Signals On 2005 Hyundai Tucson
    It is possible that a controller like the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55528 has gone bad. To test it, I recommend using a circuit tester like # PTW2993 to see the function at your 4-way when the trailer is not connected. This will help you determine if it is vehicle wiring or trailer wiring causing the issue. If the issue is with the vehicle side, you will need to replace the unit. If the 4-way is good on your vehicle test, then I...

  • Which Wire of Curt Trailer Wiring # C55528 Is for Stoplight Circuit
    On the input side of the converter box of the # C55528 there is a diagram that shows what each of the wire colors represents. The red wire is the stop light circuit, green is right turn, and yellow is left turn.

  • Does the Curt Wiring Harness # C55528 Need a Wire Run to the Vehicle Battery
    I checked your order notes and it looks like you ordered the Curt Wiring Harness part # C55528 that has been confirmed to fit your 2008 Hyundai Tucson and does NOT require a wire be run to the positive post of the vehicle battery like some harnesses do. So long story short, you aren't missing any components to your wiring kit and the harness should work well as long as you install it per the instructions that I attached to the right.
