Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

  • Constructed using surface-mount technology (SMT) for consistent, reliable performance

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.

  • Difference In Tekonsha T-One Wiring Harnesses For a 2020 Ford Edge Titanium and Other Trims

  • Difference Between Curt 4-Way Wiring that Fits 2019 Ford Edge Titanium and Tekonsha for Non-Titanium
    Since the difference between the 2019 Ford Edge Titanium and the other models is that the Titanium comes with LED taillights Tekonsha had to make a different kit with a different converter box that accommodates the difference in lighting. This is why the # C73FR fits the Titanium and the # 118805 fits the other models. Both of these are easy to install though. I attached an install video for the kit that fits your vehicle for you to check out as well.

  • 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...

  • 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.

  • 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.

    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...
