  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs into OEM tow package wiring harness. Powered converter reduces strain on wiring system. SMT construction ensures superior performance.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector

  • 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 factory tow package wiring harness, which is located behind the rear bumper, on the driver's side. Once you've plugged in the T-connector, insert the included 10-amp fuse into the integrated fuse holder.


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.


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.


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.

Couldn't be happier! Super quick shipping. Good price and clear instructions.
Only hard part was my existing frame nuts were a bit rusty and dirty and it made threading the bolts slightly difficult.

The small connector with the 2 wires will not connect and clip to lock it. Way to tight need a difference connection.

I wanted to make sure that your 2010 Hyundai Santa Fe has the factory tow package? Would you be able to send a picture of the connector that you are seeing?

2011 Hyundai Santa Fe

Works great on my 2011 Santa Fe with the OEM tow package.

Couple notes:

1. One of the factory connectors (on the car side) had an orange gasket in the connector. This prevented the connector from seating properly and locking in place. I couldn't see a reason for the gasket, so I removed it (with needle nose pliers), and it worked great.

2. The cable from the box to the 4-flat connector is really short. The only good place I could find to mount the box, left the cable too short to reach the hitch receiver. I zip tied it to the hitch bar 10" or so away from the receiver, and it works fine, but is a bit inconvenient to get to.

Direct plug and play for my 2011 Hyundai Santa Fe Limited. I made a mounting tab for the plug on the hitch receiver to keep it tucked away and clean looking.



by:

Fast and easy product was exactly as li sted



by:
2010 Hyundai Santa Fe

The Santa Fe 2010 Limited is prewired for a wire harness. There are two capped male plugs under and behind the bumper on the driver's side. They are very accessible. When you remove the caps there is a rubber seal or grommet inside. They should come out and stay inside the cap. If the grommet stays inside the male plug it will block the plugs from sliding together completely. Once the harness is plugged in it is easy to route inside the bumper. I stuck the converter to the inside of the bumper using the double stick patch. It is pretty clean there and seems secure.

  • 2009 Hyundai Santa Fe Trailer Wiring Harness Recommendation
    The only sure way to know if a vehicle came with a tow package is to contact a Hyundai dealer with your VIN. With that info they will be able to tell if your vehicle came with the tow package. If your vehicle came with a factory hitch there is a good chance you have the tow package. Or if you find the connection point for the Curt Harness part # C56346 and test the pins with a circuit tester like part # 3808 you can verify if this harness would work. It should be right under the rear of...

  • Where Does the Converter Box for Curt Wiring Harness C56346 Mount on a 2007 Hyundai Santa Fe
    The converter box for Curt wiring harness # C56346 was indeed meant to be mounted outside of the vehicle, underneath where it will be away from tire spray and the elements in general. If I may quote the instructions which I have also linked: Adhere the black converter box to the underside of the vehicle in a secure out of the way location using the double sided tape provided. Find a flat, clean surface that is out of the path of road spray from the tires. You could further protect the...

  • Parts Needed to Install the Curt Discovery Brake Controller # C51120 on a 2013 Dodge Durango
    The Curt Discovery Trailer Brake Controller, # C84VV, and the Custom Wiring Adapter, # C51446, will work on your 2013 Dodge Durango without splicing as long as your Durango came with a factory 7-way trailer connector at the trailer hitch. The 7-way trailer connector would indicate that your truck has the factory tow package, which would include a brake controller plug under the drivers side dash. You should see a gray connector just to the left of the steering column. If your Durango does...

  • Trailer Lights Work Intermittently on a 2010 Hyundai Santa Fe with Curt Trailer Wiring Harness
    It could be an issue with the trailer lights drawing more power than the wiring harness is rated for. But it also sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion...

    Both the Curt Class III Round Tube Receiver Hitch # C13073 and Draw-Tite Class III Max Frame Receiver Hitch # 75684 are confirmed to fit your 2011 Hyundai Santa Fe as long as it does not have the dual exhaust. Because of its cross tube design, the Curt Class III # C13073 is going to allow for easier access to the spare tire mounted under the vehicle. I have attached a couple of images so you can better see the comparison between the two hitches. The Curt Hitch is a great option for your...
