CURT Custom Fit Vehicle Wiring - C69KR

  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

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.


  • 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)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • 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


  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


This custom-fit T-connector plugs into your vehicle's tail light wiring connectors located in the tail light housing and accessed through the trunk and routed to the trunk light wiring which is accessed under the vehicle.

Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.

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.

2019 Toyota Prius

I purchased a Curt harness for my 2019 Toyota Prius AWD-e. The order was confirm almost immediately. The order arrived in the mail 1-1/2 days later. The instructions were clear and precise. 2 hours later, everything worked just as it should and I was pulling my ultralite utility trailer to the landfill.
Thank you etrailer and Curt.

  • Troubleshooting Trailer Lights Wiring Harness For a 2019 Prius LE Front Wheel Drive
    FWD will stand for front wheel drive. The Curt T-Connector Vehicle Wiring Harness # C56353 is the correct harness for your 2019 Prius LE front wheel drive. It sounds like the connector that mounts behind your bumper is not connected properly. This connecter is where the powered converter gets its signal for the brake lights and running lights. This is step 12 of the instructions that I have linked below for you to reference. You will not need to connect the red wire to ground as you...

  • 2022 Prius AWD Wiring Harness
    For the 2022 Prius AWD, you'll want to use the Curt # C69KR. The installation is pretty straightforward, the harness plugs inline between the vehicle's taillight wiring harnesses and taillight assemblies. One wire will need to be ran to the vehicle's start battery and connected to the positive battery terminal. I've linked to the installation instructions for you. The install should take about an hour or less, according to Curt.

  • Curt or Draw Tite Trailer Hitch Recommendation for 2022 Toyota Prius
    Both the Curt # C11473 and the Draw Tite part # 24966 that fit your 2022 Toyota Prius are really great options for trailer hitches. The edge would go to the Curt though as we have found their quality control tends to be a little bit tighter and the powder coat on their hitches holds up the best. If you needed trailer wiring too the Curt kit part # C69KR would be your best option as well.

  • Trailer Hitch and Wiring For 2020 Toyota Prius AWD-E LE and XLE Models
    I recommend to use the Curt Trailer Hitch Receiver part # C11473 for the 2020 Toyota Prius AWD-E LE which is a confirmed fit for the all wheel drive electric model of the Prius. It also fits the AWD-E XLE model as well. This will give you a Class I 1-1/4" hitch receiver on the Prius. It is a concealed cross tube design so only the receiver portion of the hitch is visible once installed for a nice clean OEM look. The wiring that is a confirmed fit for the AWD-E LE 2020 Toyota Prius, is...

  • Trailer Hitch and Ball Mount Recommendation for 2020 Toyota Prius
    In general it seems the Curt hitches have the best finish to fight corrosion so for your 2020 Toyota Prius I would recommend the # C11473. For a ball mount for Class I hitches like this you need to go with the recommended one by the manufacturer so with this hitch you'd want the part # C45521. If you needed trailer wiring too you'd want the Curt # C69KR and you'd be set.

  • What Hitch and 4-Way Wiring Harness do You Recommend for My 2022 Toyota Prius?
    For your 2022 Toyota Prius, I recommend the Curt Hitch - 1-1/4" # C11473. Not only will this hitch provide you with 2,000 pounds of gross towing weight, it also comes with a high-quality gloss outer coat over the base powder coat which gives you superior rust and corrosion resistance. It is also assembled here in the U.S.A. As far as wiring, you need specific wiring depending on what model of Prius you have. If you have front-wheel drive, you need the Curt T-Connector # C56353.

The 2" receiver is the most common size used for hitch mounted accessories such as bike racks, cargo carriers and ball mounts.

  • Trailer Hitch Receiver and Wiring Confirmed to Fit a 2022 Toyota Prius AWD-e
    I spoke to EcoHitch who confirmed that the Hidden Trailer Hitch Receiver # EH53VR will work on your 2022 Toyota Prius AWD-e. This will give you a 2" receiver which is better as more accessories will work with that size receiver. Curt has not been able to confirm that their Trailer Hitch Receiver # C11473 will fit on the AWD-e version as they have not had that model in their shop since the 2020 model year. The Curt T-Connector Vehicle Wiring Harness # C69KR will give you a 4-way flat...

    I recommend the Curt Trailer Hitch Receiver, # C11473. This is a Class I, 1-1/4" hitch that works well for light-duty towing. It is a bolt-on installation so no welding is required and comes complete with needed hardware for installation. It is rated for 200 lbs. of tongue weight and 2,000 lbs. max gross trailer weight. This will work well for towing your boat or carrying a bike rack. For needed wiring, I suggest the Curt T-Connector, # C69KR. With this, you can easily install a 4-way...

  • Hitch and Wiring Harness for Prius SE 2019 AWD
    For your Prius I recommend the Draw-Tite # 24966 Sport Frame Hitch. I think the Draw-Tite hitch is hidden better under the rear bumper fascia and does not require support straps to additionally be used. I have included a link to an install video for a 2018 model which will be the same as yours. You may find the install work a little easier with a trim pad removal tool # ALL648544 Since you are asking for a trailer light wiring harness you must want to tow a small trailer. For that you...

  • Recommended Trailer Hitch and Trailer Wiring Harness for 2021 Toyota Prius AWD-e, LE and XLE
    According to Curt, their # C11473 Class I hitch fits all models of the 2021 Toyota Prius and Prius Prime, regardless of trim level so the hitch will work great for you. For a trailer wiring harness there are two options available. For the AWD-e model, you'd use the Curt # C69KR and for front wheel drive models, use # C56353. You'll also need a ball mount like # C45521, a hitch pin like # PC2 and a trailer ball like part # 19256 for a 1-7/8 or # 19258 for a 2 inch ball.

  • Hitch Receiver Options for a 2022 Toyota Prius Prime
    I have a solution for you but I am sorry the EcoHitch Hidden Trailer Hitch Receiver item # EH53VR has a 2" receiver but it does not fit a 2022 Toyota Prius Prime. We do have the Curt item # C11473 and the Draw-Tite item # 24966 confirmed to fit your 2022 Toyota Prius Prime. However, both of these option have the 1-1/4" receiver. There are currently no options available for a 2" receiver. The 1-1/4" receivers still have a 200 lbs and 2,000 lbs towing capacity which exceeds your Prius Primes...

    Both the Curt Trailer Hitch Receiver # C11473 and Draw-Tite Sportframe Trailer Hitch Receiver # 24966 will fit on your 2021 Toyota Prius XLE AWD-e. We have received reviews for both receivers confirming fitment on their Prius XLE AWD-e models. I recommend using the Draw-Tite Sportframe Trailer Hitch Receiver # 24966 based on the construction of the receiver. The plate steel used to connect the receiver to the cross tube tells me that there is a lot more left to right rigidity versus the...
