Curt Custom Fit Vehicle Wiring - C56332

  • 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.


Features:

  • 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
  • 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 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.


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.

Perfect fit for my vehicle. Greatly reduced time and effort to install my trailer wiring. I have never liked tapping into my vehicle wiring as I know those connectors will damage the wires. This product eliminates any possible wiring problems.

The site was easy to use and search for what I wanted and needed. In addition, the DIY videos on the etrailer.com site gave me the confidence to complete the install. From installing the hitch receiver to the connection of the 4-pole wiring kit(hint: if you're vehicle has the prewiring for towing, they have the custom kits to match). Install was a snap, like 5 minutes, due to the exact fit of the product. It took out the unnecessary problem of figuring out the wiring. Thanks for everything etrailer.com! You definitely found a new customer and I will be highly recommending this site to my circle of family and friends.

A couple of challenges with installation: 1) The instructions didn't explain that the Kia factory install connectors were underneath the panels that had to be removed for the hitch installation. So it took a long time to discover where they were, and I had to take off pieces that I had reinstalled in wrapping up the hitch install. 2) On a recent camping trip, I had gone through a large washout of a road in Utah - so there was literally no place on the bottom of the Kia that wasn't covered in dried mud and there was no way to comply with the literal instructions to install the control panel some place that it wouldn't be splashed. The cables were a bit on the short side, but I think they'll be workable. I'll probably have to let out some of the slack on the trailer side.

Very easy to install on a 2019 Kia Sorento with the factory tow package. It plugs right into the factory connectors. For the 4 Pole Flat connector I used bracket 18144 since the wire is fairly short. It looks clean and professional. This bracket attaches directly to the no-drill bracket already present on Draw-Tite hitch receivers. To check if your vehicle has the tow package you just need to pop out the 2 plastic rivets on the driver side panel shown in the install video and see if the 2 connectors are present. I was not able to confirm through the dealer or Kia corporate which Sorentos have the factory tow package.

Can you say plug and play.....well in this case it was plug it in and light em up. My Sante Fe Sport was prewired and the harness that I purchased from y'all matched up perfectly..... it's been 1 year and I have had ZERO issues. Installation for this item was about 45 minutes. So.....in less than 2 hours I had installed my receiver hitch and the wiring harness (by myself in the driveway). Thanks again for a good product at a really good price. My apologies for not having any pics....

The wiring harness worked great and the videos helped a lot. I did fry the fuse testing the connections but only because I had my tester set on a much higher amperage than it could handle and the fuse worked like it was supposed to. Was truly plug and play once I gained access to my already installed equipment.


Comments
Still working great. We use the hitch all the time but not so much the wiring harness. I wish larger bike racks came with built-in brake and turn signal lights that I could utilize my harness for but thats another subject all together.

  • Wiring Needed to Add a Brake Controller on a 2013 Hyundai Santa Fe
    The Curt T-Connector # C56332 that you referenced actually doesn't carry the brake controller signal. It tees into your vehicle wiring and only carries the basic trailer lighting functions. If you are trying to tie in a Tekonsha brake controller, like the Prodigy P3 # 90195, then you also need the Universal Wiring Kit # ETBC7. This plugs into the Curt T-Connector and comes with all of the wiring and parts needed for a fully functioning 7-Way. I have attached an installation video of...

  • 2016 Hyundai Santa Fe Sport 2.0T Trailer Wiring Recommendation
    Not every 2016 Hyundai Santa Fe Sport came with the factory towing package. If yours did (it would have a hitch at the rear of it from the factory) the Curt wiring harness part # C56332 would fit and work well. If you did not have the factory tow package you'd instead need the part # C56184 which installs by plugging inline with the taillight connectors of the vehicle. This also would fit vehicles with the tow package too.

  • Correct Trailer Wiring Harness Confirmed to Fit a 2018 Chrysler Pacifica Hybrid Limited
    You are correct that the Curt # C56332 does not fit a 2018 Chrysler Pacifica. The correct Curt wiring for your van is # C56322. I'm guessing the error was made because of how close the part numbers are to each other. With that being said I recommend using the Tekonsha wiring, part # 118712, that's also confirmed to fit your Pacifica. We usually find the Tekonsha wiring harnesses to be of better quality than the Curt products. If you don't already have a hitch Curt offers a Class...
