Install a 4-way flat on your vehicle 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.

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

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.

Easy to install even if you know nothing about wiring the YouTube video with step by step instructions makes this wiring harness easy to install

Was easy to install and still works Great

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.

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!

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.

Great service from order placement to shipping. Installation without a hitch and any questions were quickly answered by instructions or you tube video. Make sure to habe the right tool for the plastic rivets.

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.

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.

Everything was there that I need to wire my Camry for my little trailer along with the hitch I order. Perfect fit just like they said it would be. Everything I've ordered from them has been as they said it would be. Very happy with this compamy.

- 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.

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.

This worked for our 2006 Scion xa. It was a lot more complicated than we had expected and took my electrically savvy husband most of a day to figure out how to install it, using several videos. But it was the right kit and we will be able to haul our light trailer.

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.

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!

The Who package is very well made. From the box that looks high end to the inner product that is well built. I had everything you need to install for the product to work, you’ll only need a probe tester and basic common electrical knowledge to hook up the product. I received the product that I paid for the shipping method which is for 2 days. I installed it and now I’m a happy 1st time trailer puller.

I have no complaint with your products and the speed getting it shipped. Job well done. My complaint is the time in transit and is very much a part of the total customer experience. Using USPS for shipping is almost a guarantee that the shipment will be late. Giving the customer a choice of paying more to get an “expedited” shipment is shifting the blame to the customer if it doesn’t arrive on time; regardless of how it’s shipped. [other] vendors ship free and the cost is included in the price of the product. It makes it easier and more efficient and the company doesn’t have to guess at which service to use in order to get the product to the customer on time. My order was shipped Priority 3 Day. It was ordered on the 23rd of February and was delivered today. The post office works on Saturday so that counts as a working day. That means it was delivered 3 days late! While that doesn’t seem like much, if you have someone’s automobile with a hitch already installed (purchased from you) and the rear of the car dissembled for the wiring install, it’s an eternity for the owner. I’m sure you can bring this to your company leadership and come up with a shipping plan that eliminates the guesswork and doesn’t allow the customer to pick the wrong shipping method. Just ship it free by one of the reliable carriers, add it to the price and allow the postal department to what they’re good at; bulk mail.

Installation stretched my limits, but we will blame that on the car and on my narrow limits. It is a tight and clean install. Has worked flawlessly this past year. I used it just yesterday to haul junk and brush about 100 miles for disposal. I would definitely buy this hitch again.

BMW X1s don't come with a trailer hitch. There is no factory option. So, if you want to tow a trailer or just a bike rack, you have to pay big bucks or get your hands dirty. I chose the latter and am enjoying the fruits of my labor. Etrailer's Draw-Tite MaxFrame 75761 was a perfect, if tight, fit. To make it work you need to temporarily undo some of BMW's bumper support and manhandle the mounting brackets onto the bolts past the muffler. The most difficult task is tightening the bolts. A flat ratchet, rather than a socket set is almost a must. When you are done, you have a unobtrusive factory look. It helps with the wiring that on the 2013-15 X1 the battery is in the back and you don't need to run the cables into the engine compartment in the front. I have used my trailer hitch now for over a year without problems for bike racks, utility and motorcycle trailers. Fully satisfied.

One year in, the hitch is working as good as on day one. There is some slight rust, but that is more due to the numerous times I hae installed and taken off a 4 bike rack. Nothing a little TLC cant fix. I have also towed trailers locally and cross country without any issues. Still fully satisfied.

  • 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,...

Multiple lights are generally installed to a trailer with a single ground source. With your situation, you will need to have a dedicated ground for each light. This should cause the run off to dissipate into the frame and solve the pulsing issue.

  • No Power to 4-Way on 2011 Audi Q5 with Curt Wiring Harness
    The most common issue we see when using the Curt Powered Tail Light Converter part # C59236 on a vehicle with tail lights in the rear hatch like on your 2011 Audi Q5 is testing the 4-way with the hatch open.

    The trailer wiring harness I recommend for a 2009 Kia Sportage 4-Cylinder is the Curt Powered Tail Light Converter part # C59236.
