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.

excellent hitch and wiring kit worked perfectly to interface with my Ford Edge.
Removing the tail light was difficult. One screw. Pulls off.
Had to add duct tape as shown to pull the tail lights free. Careful. The lights are expensive.

My husband and I have been dealing more and more with our own DIY car repairs -- thanks for this awesome duct tape idea! Glad to hear the wiring worked out well, too :) Thanks, Stacy

Super easy install on my 2019 Edge Titanium. I found a model online and 3D printed a mount with PETG for the wiring connector. Really classy looking installation!

    You are correct, the Curt T-Connector Vehicle Wiring Harness # C56272 is not a fit for a 2019 Ford Edge; this harness is only a fit for 2015-2018 Ford Edge SE and SEL models; whoever told you it did fit your vehicle was mistaken.

    Yes, we do! To add a hitch to your 2024 Ford Edge, I recommend the etrailer item # e36RR. This hitch is custom fit and bolts to your Ford with included hardware. This hitch fits all models of the 2024 Edge including the Titanium, SEL, and SE. I really like this hitch because the crosstube mounts behind your rear bumper cover leaving only the 2" receiver exposed. This not only helps with ground clearance but it looks better. On top of that the flat matte finish will blend in better beneath...

    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.

  • Which Hitch for 2019 Ford Edge Does Not Require Heat Shield Removal
    I can understand your concern; thankfully, I can offer a couple solutions. The Draw-Tite Trailer Hitch Receiver # 75234 states that only the Sport model of the Edge requires the heat shield to be removed permanently. However, when we installed it on a 2018 Ford Edge Titanium (non Sport), we found that it also required the heat shield to be removed and it cannot be modified or re-installed. The reason this is the case for the # 75234 is because it's designed to fit more snugly against your...

  • 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.

  • Will Installed Trailer Hitch Block Hands-Free Liftgate Feature on 2019 Ford Edge
    Actually, all of the hitches available for the 2019 Ford Edge, regardless of trim level will have the sensors for the Hands-Free liftgate feature blocked at the middle of the bumper. This is because the receiver tube extends below the bumper and would sit between where you'd sweep your foot and the liftgate sensor. The system uses 3 or 4 sensors (depends on the vehicle) and the sensors will still pick up movement but you'll need to sweep your foot to the left or right of the center of the...

The Draw-Tite hitch has a hidden design like you are looking for which means the cross tube is hidden and only the receiver tube will be shown. This also ensures that you don't loose too much ground clearance.

    The tail light connectors are different on the 2020 Ford Edge Titanium from the other trims. You can see in the images I put below that the tabs off the connectors are in different places. The Curt T-Connector # C73FR for the Titanium has black connectors with the tabs at the corners. While the Tekonsha T-One # 118805 for other trims has tan connectors and the one tab is right next to the latching tab.

    I would be happy to help. To control a trailer's brakes with your 2019 Ford Edge Titanium you're going to need a 7-way connector and a brake controller. There isn't one harness made specifically that will do this so you will need two separate wiring harnesses. The first harness you will need is the Curt T-Connector Vehicle Wiring Harness item # C73FR.

    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...

  • 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.
