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 tail light assemblies 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 flat 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.

  • Most Concealed Hitch for a 2023 Ford Edge
    The most concealed hitch for your 2023 Ford Edge is going to be the Draw-Tite Trailer Hitch item # 75234. This hitch is custom fit and bolts to your Ford with included hardware. I really like the Draw-Tite hitch because it installs just below your rear bumper cover, leaving only the receiver and safety hooks visible. This is a class III hitch with a 2" receiver. It has a 4,500 lbs towing capacity, and a 675 lbs maximum tongue weight. I have linked a couple of pictures below along with...

  • Do I Have to Remove the Bumper Cover When Installing a Hitch on a 2023 Ford Edge?
    No, it does not. The Curt Hitch item # C78KR does not require you to remove your rear bumper cover when installing it on a 2023 Ford Edge. It bolts to the bottom of the frame and the crosstube is concealed behind the bumper cover. I have an alternate suggestion for a hitch. Instead of the Curt item # C78KR, I recommend the etrailer Hitch item # e36RR. These hitches are identical with the exception of cost and the paint finish. The item # e36RR is our house brand hitch but it is made by...

  • Hitch and Wiring Harness for a 2022 Ford Edge Titanium
    Yes, we do have a hitch for your 2022 Ford Edge Titanium. It is the Curt Trailer Hitch Receiver item # C78KR. This hitch is custom fit and bolts directly to your Ford's frame with included hardware. For your wiring harness I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C73FR. This custom-fit T-One connector plugs into your Edge's wiring harness behind the rear tail lights. To round out your towing setup I recommend the Curt Towing Starter...

  • Curt Trailer Hitch Receiver C13234 Compatibility 2019 Ford Edge Titanium and Hands Free Lift Gate
    Yes, the Curt Trailer Hitch Receiver # C13234 will fit your 2019 Ford Edge Titanium. If you have the hands free lift gate you will still be able to use it but the area will be more limited as seen in the installation video that I have linked below. I recommend installing the Curt T-Connector Vehicle Wiring Harness # C73FR when you install the receiver. This will give you a 4-way flat connector that allows you to control the lights on most small trailers and will also allow for Auxiliary...

  • Recommended Trailer Wiring Harness Fit for 2020 Ford Edge ST Line
    According to Curt, the # C73FR trailer wiring harness will only fit 2020 Ford Edge models in the Titanium trim. For all other trim levels including the ST Line, you'd use the Tekonsha # 118805. If you click the provided link, you can see an informational review video.

  • I do have a solution for you, but after looking at the online owners manual for the 2021 Ford Edge, it does not appear that they equip these with a factory brake control port. So I would not be able to offer you a plug and play harness for the Tekonsha Prodigy P3 # 90195 at this time. We can definitely still help get your brake controller installed. If you are in need of a 4-pin harness, we have part # C89FR which will fit SE and SEL models, Or part # C73FR which is for the Titanium...

  • Recommended Trailer Hitch and 7-Way Wiring Harness for a 2020 Ford Edge Titanium
    The best trailer hitch option for a 2020 Ford Edge is the etrailer Trailer Hitch Receiver part # e36RR which offers a custom bolt-on fit without any drilling required. It has a hidden design so you'll only be able to see the receiver under the vehicle, not the crosstube which makes for the best overall appearance. It will work great for hitch mounted accessories or towing. If you will be towing then you'll also need a few other items such as a wiring harness, I recommend the Curt T-Connector...

  • Does the Lift Gate Function Still Work w/ the etrailer Hitch e34AR Installed on a 2023 Ford Edge?
    The hands free lift gate will still function when the etrailer Hitch item # e34AR is installed. Some of the range will be lost specifically around the 2" x 2" receiver. You will want to move your leg to the left or right of the hitch receiver to get it to work. The etrailer Hitch item # e34AR is confirmed to fit your 2023 Ford Edge. It is custom fit and bolts to your Edge with included hardware. This is a class III hitch with a 2" receiver that is made in the USA. It has a 4,000 lbs towing...

  • Trailer Hitch Receiver and Wiring Harness for 2020 Ford Edge Titanium
    The Draw-Tite Max-Frame Trailer Hitch Receiver is confirmed to fit your 2020 Ford Edge Titanium with hands free liftgate. Keep in mind, this will likely limit the functionality of the kick sensor so you will need to find the right spot on either side of the receiver to activate it. The same is true for any hitch you choose to install on your vehicle. Also yes, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C73FR is the correct wiring harness for the Titanium....

  • What Wiring Is Needed To Install a 7-Way and Prodigy P3 on a 2024 Ford Edge Titanium?
    We have the 7-Way Kit # ETBC7 which will provide you with the wiring you need to install your Tekonsha Prodigy P3 # 90195 on your 2024 Ford Edge Titanium. This will plug into either your currrent 4-way or we have the Curt 4-Way # C73FR if you do not already have the factory wiring. If you also need a receiver I recommend our etrailer Trailer Hitch Receiver # e36RR. I find this looks the best with the matte black finish.

  • Will Installing Trailer Hitch on 2009 Ford Edge Cause Hands-Free Liftgate Not to Work
    Installation of the Draw-Tite # 75234 Class III hitch on your 2019 Ford Edge will block a portion of where the sensors can 'see', but the liftgate will still function. Usually on the Ford vehicles, the areas about 3-6 inches to the right and left of the receiver tube over to the corners of the vehicle will still work just fine. I do know that some vehicle manufacturers like Honda offer relocation brackets for the liftgate sensors, but I have not been able to find anything for the 2019...

  • Will Curt Trailer Hitch Receiver 13452 Fit 2023 Ford Edge
    Yes, the Curt Trailer Hitch Receiver # C78KR (13452) is confirmed to fit your 2023 Ford Edge. This Class III hitch features a concealed cross tube and a bolt-on installation. It also comes with a limited lifetime warranty. If you plan on doing some towing you'll also need wiring. The most reliable option is the Tekonsha T-One Vehicle Wiring Harness # 118805. This plugs into the connection points behind your taillights and will provide you with a 4-way to power your trailer's signal lights....

  • Troubleshooting Blinker Hyperflash On 2019 Ford Edge Titanium After Shop Installed Trailer Wiring
    It doesn't sound like the hitch install would cause the wiring issues. More than likely you also had a trailer wiring harness added as well like the part # C73FR on the Edge Titanium. There is a few reasons why your left blinker could be hyper flashing. It could be an issue with the ground of the wiring. You want to make sure there is a good ground to a clean bare metal surface of the vehicle's frame. The harness may not be fully seated with the correct plug. If that is the case, they will...

  • Does the Draw-Tite # 75234 Allow Me to Use My Hands-Free Liftgate Sensor on My 2021 Ford Edge?
    Yes! The Draw-Tite Hitch # 75234 will work with your hands-free liftgate sensor on your 2021 Ford Edge. You will just need to have a little wider kick to activate the sensor once the hitch is installed. If you plan on towing with the hitch, I recommend a ball/ball mount like the ones included in the Curt Towing Starter Kit # C45534. Not only does this kit come with a hitch cover, but it also comes with a locking hitch pin. Also, if you need trailer wiring, I recommend the following harnesses...
