Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the trunk floor coverings, storage trays, and the rear and side scuff panels to access this harness. Once you've plugged in the T-connector, run the hot lead 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.


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.


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.

  • Can Curt Trailer Hitch C11567 Be Used To Tow 589lb Trailer W/ 2020 Toyota Corolla Hatchback SE?
    The Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C11567 you were looking at for your 2020 Toyota Corolla Hatchback SE has a 200lb tongue weight rating and a 2000lb trailer weight rating so in that regards the hitch will not have any problems with your 589lb trailer. Since Toyota and the trailer manufacturer told you there would be no issue, and the hitch has the correct ratings for the trailer I cannot see any problems you would run into. Regarding sway, that comes down...

  • Can the Curt Trailer Hitch Handle a 1,000 Pound Trailer Towed With a 2021 Corolla Hatchback
    The Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C11567 has a maximum gross trailer weight of 2,000 lbs and tongue weight of 200 lbs. This means it will be able to handle towing your 1,000 lb trailer without any issues. I would also make sure to consult the owner's manual so you know the towing capacity of your vehicle. You will be limited by whichever is lower, the vehicle or hitch capacity. Since you will be towing a trailer you will also need wiring, the Vehicle Wiring...

  • Recommended Trailer Hitch For 2016 Scion iM
    The trailer hitch we offer for your iM is the Curt Trailer Hitch, part # C11420. This is a Class l hitch and it has a 1-1/4 inch receiver opening. This will work great for light towing. Curt requires a stabilizing strap like part # 18050 to be used for any non-trailer items used in the trailer hitch. If you need a 1-7/8 inch hitch ball I recommend the Euro style drawbar, part # C45571 and for a 2-inch you can use part # C45572. for a trailer wiring harness you can use part # C56309.

  • Trailer Hitch Recommendation for 2017 Toyota Corolla im
    The Curt trailer hitch part # C11420 has a 2,000 lb trailer towing capacity which would easily be enough capacity for a stand up jet ski or dirt bike since those vehicles and the trailer associated with them are pretty small and lightweight. I attached an install video for this for you to check out as well. You would want to check the owners manual of the vehicle to be sure it has the capacity for the trailer as well. The overall towing capacity for a vehicle is that of the lowest rated...

  • Trailer Hitch Installation for 2022 Toyota Corolla Hatchback
    We don't have footage of the Curt # C11567 Class I hitch being installed on a 2022 Corolla hatchback but we do have a video of it being installed on a 2020 model, see the link. I've spoke with my contact in the engineering department at Curt, who tells me that the procedure for installing the hitch on a 2022 model would be the same as the 2020 model shown in the linked video. If you'll also be using the hitch for light duty towing, you'll also need a trailer wiring harness like # C56309,...

  • Recommended Trailer Hitch And Wiring For A 2024 Toyota Corolla SE Hatchback
    Hey Fred, For a 2023 Toyota Corolla Hatchback you'd be able to install the Curt Trailer Hitch Receiver # C11567 that you were already looking at. From there you would want to measure the distance from the bottom of the trailer coupler to the top of the inside of the trailer hitch receiver to see what kind of rise you'd need to keep the trailer level while towing. Once we know what rise you'll need we can find the right ball mount. You'll also want to pick up the Curt T-Connector Vehicle...
