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 interior trim panels in your rear cargo area. 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.

  • Estimated Time to Install Curt T-Connector Vehicle Wiring Harness Part # C55373 on 2000 Lincoln LS
    I have looked over the installation details for the Curt T-Connector wiring harness, part # C55373. Due to the fact that the battery is located in the trunk, I would estimate that a reasonably handy individual could easily complete the install in less than an hour. Other than one connection to the battery, this is pretty much a plug-and-play type installation. To view the install details, click on the provided link.

  • Trailer Hitch for 2005 Lincoln LS for Carrying Small Trailer for Heavy Scooter
    I am not sure what 2005 Lincoln you have, but if it's a 2005 Lincoln LS like what the Curt hitch part # C12253 you referenced is designed to fit the answer would be "no it could not carry a 500 lb scooter on a hitch mounted carrier." The only solution with this vehicle would be with a small trailer towed with this hitch installed. For trailer wiring you'd then need the part # C55373 which I recommend as it installs easily and is very reliable, and then for a ball mount # 36071 with hitch...

  • Troubleshooting Trailer Wiring Malfunction in 2000 Lincoln LS
    The wiring harness we offer for your 2000 Lincoln LS is part # C55373 from Curt, it has a 12V power wire that needs to be run up to the car's battery to deliver the actual power for the trailer lights. The Curt harness you referenced, part # C56160, works the same way, although it is NOT a confirmed fit for your 2000 Lincoln LS (it fits the MKX only). Hopefully this is not the harness that was installed. Based on the (very) odd behavior of your trailer's driver-side brake light, it sounds...

  • Parts Needed to Add a Pilot Trailer Brake Controller to a 2001 Lincoln LS
    First, you are going to want to check the owner's manual for the 2001 Lincoln LS to determine the towing capacity of the vehicle and not exceed it. After that, you will start with adding a 4-Way trailer wiring harness. It sounds like that is what you already have. The one we carry for your car is # C55373. It is a powered converter that requires a direct connection to the vehicle battery to supply most of the power to the trailer lights. With the 4-Way installed, you would then need to...

  • Trailer Light Turns On After 20 Minutes of Turning Off Tow Vehicle, a 2000 Lincoln LS
    I spoke with my contact at Curt about the Wiring Harness, # C55373, on your 2000 Lincoln LS. The good news is that there is nothing wrong with the wiring harness. What is happening is that on your model vehicle (and a handful of others) there is what is called a battery saver mode that kicks in about 20 minutes after the vehicle has been turned off. With the trailer connected, it thinks that it still needs to deliver power and that will cause the light to light up on the trailer. My...
