    2- And 3-Wire Systems

    Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring.


    If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights.


    Note: This will not affect how the tail lights on your vehicle operate.


    Powered Tail Light Converter with Surface-Mount Technology

    Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring.


    If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights.


    Note: This will not affect how the tail lights on your vehicle operate.


    Curt SMT Circuit Boards

    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.


    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.


    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.


    Installation

    To determine where to splice into your vehicle's tail light wiring, you will need to consult the included instructions. Use the quick-splice connectors to attach the input wires of the tail light converter to the corresponding wires from your vehicle. To get the power necessary to operate, the harness must be connected to a 12V power source. To do this, you will need the Curt powered converter wiring kit (55151 - sold separately), which contains the power wire that connects your battery.


    Then locate a flat surface inside your vehicle near the tail lights and adhere the black converter box using the provided double-sided tape. Find a raw metal surface to use as a ground point and secure the white ground wire using the provided ring terminal and screw. Finally, secure the converter wires to your vehicle using the included cable ties.


    It is recommended that you use a small amount of dielectric grease on the 4-pole connector to help prevent corrosion.

    • Recommended Brake Controller For A 2007 Monaco Dynasty
      Hey Danniel, If you don't already have a 7-way or 4-way on the back of your motorhome then you'll need to start with the Curt 4-Way Flat Trailer Connector with Circuit Protected Powered Tail Light Converter # C85FV. This will splice into your factory tail light wiring and run up to the battery for power. From there you can install the # ETBC7 7-way kit. This will plug into the 4-pole wire harness for the lights and have wires to run to power/ground and up to the brake controller. Once...

    • Will Curt Trailer Wiring C85FV Trigger Trailer Connected Message
      Yes, if you installed the Curt trailer wiring kit part # C85FV on your 2023 Ford Maverick it would NOT trigger the trailer attachment message. This is because it does not tie into to factory trailer wiring where that message originates.

    • Can I Add A 4-flat Connector To The Back Of My Camper For Double Towing?
      Hello and thanks for getting in touch. It is possible to add a 4-pin connector to the back of your camper for double towing. To hook up the lighting you will need to use junction box # 38656 along with 4-flat connector # HM48035, which you can mount with brackets # 18144 and # 18140. You are going to run the lights from your camper to the junction box and then to the 4-flat connector. You may need extra wire # DW02923-1 and butt connectors # 05730-5 as well.

    • Does Trailer Wiring Power Wire Have to Run Up to Vehicle Battery
      Hey Edo, so the reason you want to run the power wire of the Curt 4-way part # C85FV all the way up to the battery is because this prevents the possibility of any trailer wiring shorts from affecting the taillight circuits of the vehicle. This is only safe way we can recommend you install the harness.
