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 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.

  • 4-Way Wiring for 2022 Ford F-150 With Backup Sensors and Incandescent Lights
    The only company that makes a plug and play 4-way compatible with backup sensors is Curt and it is the # C63NR. I'm guessing you already found this and saw it is only compatible with LED tail lights. You can either splice-in the # 18252 or swap out the tail lights for LED to use the Curt. Unfortunately, nobody makes a plug and play wiring harness that will work with the backup sensors and incandescent lights.

  • Can Curt T-Connector be Used to Activate 2021 Ford F-150 Tail Lights for Flat Towing
    The Curt T-Connector # C63NR you're installing on your 2021 Ford F-150 is designed to send power to a trailer, but for a flat tow setup you need a wiring harness designed to receive power, and for that I recommend the Roadmaster diode kit: - Hybrid # RM-15267 - non-Hybrid # RM26FR Both parts are installed by splicing into the wiring on your truck and gives you everything you need to get the power from the RV plug back to the tail lights on your F-150.

  • Will The Curt T-Connector C63NR Fit A 2024 Ford F150 XLT?
    Hello and thanks for reaching out. The Curt T-Connector # C63NR will indeed fit on your 2024 Ford F150 XLT. Just like you said it will plug in behind the tail lights and you will run a wire to the battery to power the converter module. Keep in mind that this is a 4 flat connector, so you get brake lights, running lights and turn signals. The 4-flat does not have a reverse light function.

  • Trailer Hitch and Wiring for 2022 Ford F-150 Without Factory Tow Package
    Hi Alexander; assuming you have the factory step bumper you can use the Draw-Tite Ultra Frame Trailer Hitch Receiver # DT35MR you were looking at. For the wiring, I would check to see if you have the factory wiring harness plugged into the back of the dummy plug on your bumper. If you do you can pull the dummy plug and add the # HM40975. If it doesn't work as is, you may have to run it by the dealer to activate the tow package circuits. If you do not have any factory wiring we will have...

  • Help Identifying Plug On Bumper Of A 2021 Ford F-150 & Wiring Harness Options
    Hello Leslie, I can definitely help with this. So, the plug in your picture is not actually an electrical plug at all. The plug you are seeing is for lowering the spare tire. Your remove it with the key to allow access to the spare tire. Since you do not have any trailer wiring currently you will need two wiring kits for a 4-way and a 7-way. You will need the Curt T-Connector # C63NR as well as the Universal Installation Kit # ETBC7. This will be everything you need to install a 7-way,...

  • Parts Needed To Add A Secondary 4-Pole Connector For A Trailer Hitch Light
    Hey Damion, The Curt T-Connector Vehicle Wiring Harness # C63NR would be a compatible fit for your 2024 Ford F-150. This plugs into your tail light wiring and would require you to run a wire up to the battery for power. For a cleaner look you could probably just swap out your factory 7-way with the Reese Multi-Plug Wiring Harness for Factory Tow Package # 74682, which would have a 4-way connector for your light as well. This would plug into the factory 7-way wiring so the only modification...
