  • Plug and Lead
  • CURT

Install a 4-way flat on your GMC Yukon with this splice-in harness. Powered converter connects directly to battery to reduce strain on wiring. Potted, SMT construction boosts water and vibration resistance. Works with 2-wire, 3-wire, and PWM systems.


  • 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)
  • Ensures that your vehicle's wiring matches that of your trailer
    • Works with 2-wire, 3-wire and pulse-width modulation (PWM) systems
  • Connects directly to your battery to avoid overloading your 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
  • Resists water and vibration thanks to potted enclosure
  • Connects directly to your vehicle's wiring with the included quick-splice connectors
    • Color-coded wires and wiring guide ease installation
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • Limited 1-year warranty


To determine where to splice into your vehicle's tail light wiring, you will need to consult the included instructions. Use the quick-splice connectors to attach the input wires of the tail light converter to the corresponding wires from your vehicle. Once you've spliced in the converter, connect the included hot lead to the black wire and run it 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.

Then locate a flat surface inside your vehicle near the tail lights and adhere the black converter box using the provided double-sided tape. Find a raw metal surface to use as a ground point and secure the white ground wire using the provided ring terminal and screw. Finally, secure the converter wires to your vehicle using the included cable ties.

It is recommended that you use a small amount of grease on the 4-pole connector to help prevent corrosion.

Powered Tail Light Converter with Surface-Mount Technology

Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring. If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights. This converter will also ensure that your trailer's lights illuminate fully, even if your vehicle has pulse-width modulation (PWM) wiring. Note: This will not affect how the tail lights on your vehicle operate.

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.

2019 Volkswagen Golf SportWagen

I tried to follow the directions and code the wires to the car's function. The brake/directional were on the same wire and easy. However, the taillight was testing on two of the remaining wires. I called for clarification and was given the incorrect wire by two different techs. I had to cut that wire and attach to the remaining wire and everything appears to be working properly now.

One year later and about 3000 miles on the wiring, everything is working as it should. It is scary to close the tailgate on the wiring, but appears to be okay. Just dont get it near the latch!

2007 BMW X5

I would not have been able to successfully install the hitch and harness without the tech video instructions. It was nearly identical to my 2007 BMW X5. I just had problems putting in the ground screw because the instruction video placed it under where there is a plastic pocket reservoir, and I had to improvise because I did not know how to remove it, so, I had to drill a small hole at an angle and try to screw the ground screw in level by the help of the angled starter hole, and it worked. The reflectors were a bit challenging because of having to contour my arm and hand around the mufflers to squeeze the clips. The harness green wire was barely long enough, but, all in all, everything worked out great, especially, for someone like myself who does not have a mechanical leaning in personality.

2010 Audi Q5

Kit worked well on our 2010 Audi Q5. Don’t follow Tim S. Wiring suggestions. They didn’t work for my Q5. I had to rewire it with different connections as his were all wrong for my car. I included a picture of what worked for me.

- C59236

Product was exactly as described and easy to install. It works perfectly. Installation told 35 minutes. Suggestion for etrailer…The kit only includes one eye ring fastener pre-attached to the white module ground wire. Given that the red module wire will almost always be grounded too, they should include a second eye ring connector. Luckily I had one in my shop.

2013 Audi Q5

Pretty straight forward install on a 2013 Audi Q5 S-Line. There is an ground lug on the rear inside panel right next to a convenient spot to mount the unit. I removed the silver panel along the tailgate sill to route the power wire and the trailer plug tail before I started. It clips off easily, and you can reach between the side panel and the battery compartment with your fingers. There's a small electrical connector on the panel, so be careful to disconnect it before yanking on it. Make sure you replace this panel as soon as you have routed the wires, as that electrical connector is to two micro switches that detect if the door is closed... there is no power to the rear lights while the tailgate is up, so this panel needs to be in place before you start wiring. Correct wires were easy to locate. The 2013 Q5 is a little different to the wiring types listed in the instructions, as while the brake runs off the turn signals, there is a separate tail light wire. If you are probing for the wires, close the tailgate, and climb in through the rear passenger door. Here are the correct splices off the tan connector... Tail Light (Brown) - splice to Black with Green trace Left Signal (Yellow) - splice to Gray with Black Trace Right Signal (Green) - splice to Gray with Blue trace Red and White both Grounded together. The only issue I had was that the blue splice connectors supplied are too big for the fine wires on the Audi, so when I tested the install, I had nothing working. I replaced the blue connectors with the smaller red ones, and all worked perfectly then. Start to finish, about 90 minutes.

2021 Toyota Highlander

There needs to be a 2021 Toyota Highlander specific set of instructions, or even better a video. First off, the battery is located behind the right rear wheel well, key points being being the heavier guage battery wire supplied only needed to be about 18" long, as best space available for control module is right next to the battery. Because of that, the long signal wire should be the left side, not the right side, but as the only reasonable place to splice in brake, turn and running lights is at the rear lighting housings, a little primer on removing / replacing them without scratching your paint would help the newbies. Getting wiring from the battery area to the taillight housings could use some clearer instructions. Basically the included instructions, and to a good degree the kit, are a bit too generic for the newer Highlanders.

- C59236

Pretty straightforward installation. Just had to do some research to determine which wires were the right ones for the turn signals on my car. The newer cars with CANN bus systems have made it difficult for plug and play type adapters so this is the next best thing. But, price gets high when you have to use a module. I ordered this along with the hitch and they were both in the same large box. Box was damaged and opened, then re taped closed. The wiring module was out of its packaging and all the pieces were all over the larger box. Luckily everything was there and I got it installed rather quickly.

2012 Chevrolet Volt

The wiring kit was complete, solid construction, clear directions, and worked very well. This was my first time wiring a car for a trailer. I was lucky that there was already a 12 volt power line running near my trunk auxiliary power/cigarette lighter plug), so it was easier than I was expecting. It’s been a year now, and it’s been no issues yet. I don’t remember how much I paid for the kit, but it must have been close in price to others - and it has been a super value for me

- C59236

The powered tail light converter makes the lights on both trailer and the vehicle perform as if it were factory installed. The only drawback is the wiring instructions were a bit confusing. The person who helped with the installation is a professional auto mechanic, and we had a bit of trouble decifering which wires went where. It came down to using a bit of trial and error at the end to get it right. But once we figured out out, it works great. Overall, a very good item.

2009 bmw 528i. you almost can't see the trailer hitch below the bumper. I've NEVER seen a Beemer pulling a trailer............. Electrical hookup was just as the instructions said. BMW has the battery in the right side of the trunk so power hookup was easy. I put the pig-tail down in the spare tire well when not in use. Feel free to use whatever pics you see fit. Great product and install videos.

- C59236

Took me a while to get around to installing the hitch and wires, but when I needed to tow, I had all the components bolted onto my car and I was cleaned up within an hour! Wires took a little longer, but only because I triple-watched the youtube etrailer supplied. Although the model of car they showed was different from my own, I was able to figure it out quickly and confidently. Five stars!

- C59236

This is unnecessary work for a 2021 Toyota Highlander Limited. The vehicle has a plug-in for a converter behind the left rear interior quarter panel. Also there is a plug-in under the rear bumper cover on the left for your trailer wiring harness. You need etrailer part TK99FR, which gives you an easy plug-in converter, and the wiring harness for the rear of the vehicle. Done!

2013 Ford C-Max

I finished the installation of the hitch and wiring harness last night. I left turn signal wasn't working but that's because I didn't secure the wire properly in the butt connector. The only suggestion I would make is when they tell you to use tape so you won't scratch your paint from the tail light I would suggest using a soft rag or paper towel because the tape left gum on my paint now I need to remove that. The videos were a big help. Everything works fine looks good.

Really well. I use the to tow a motorcycle trailer with a single motorcycle. No complaints works excellent.

Works great, straight-forward install.

Replaced it. The control box was directly behind rear tire. I think water and road salt got in and messed up the controls. I got the same harness but sealed where the wires came in.

About a year ago I installed this wiring set on my wife's 2020 Kia Soul with LED tail lights. The process was a little more complicated due to the LED option on the car, but with basic tools and skills it was not difficult. The result is perfect and allows me to pull a small trailer with the car with all lights working perfectly.

- C59236

The etrailer video was very helpful for the install. My only complaint is that the wire that runs from the control box to the passenger tail light could be 6” longer. I simply spliced it to a lower point on the tail light harness. Still made for a clean and hidden install.

- C59236

worked great.had it installed by professional and no problems. use it a lot. however, the wiring harness was the wrong one but the pro was able to fix the problem. need better info for wiring.

Hi Charles, Thanks for your feedback! This wiring harness is designed to fit in your 2020 Kia Soul as long as you have the LED light package.

  • What is the Difference Between Curt Wiring Harnesses # C56175 and # C59236?
    Both the Curt # C56175 and # C59236 will add a 4-way trailer connector to your 2006 Volkswagen Golf. The main difference between these products is that the # C59236 is a powered tail light converter, which means it gets wired to your vehicle's battery instead of only receiving power from your vehicle's tail light circuit. Basically, what this does is limit the power drawn from the tail light wiring to isolate your vehicle wiring from your trailer wiring. In case there is an overdraw situation,...
