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.

  • Recommended Hitch and Wiring Harness for a 2027 Kia Telluride
    Hey Bryan, congrats on your new SUV. As of (05/13/26) the Curt Hitch item # C82RJ and the Curt 4-Way connector item # C34MJ are the only parts we know of that are going to be coming out for the new 2027 Kia Tellurides. It's super early in the year though and I am sure shortly after your new Kia gets released we'll have some new information on what's available for it. You bought a really popular towing vehicle so I am sure there's going to be an aftermarket 7-way for it. I don't have any...

  • Trailer Hitch and Wiring for 2027 Kia Telluride
    Hey Ricardo! Yes, the Curt Trailer Hitch Receiver # C82RJ is the hitch Curt is working on for the new 2027 Telluride. This is a pre-order since Curt hasn't finished the design. It does not include wiring. The wiring harness for the 2027 is also up for pre-order # C34MJ. We do not have an ETA on either of these parts. If you have an immediate need for a hitch and wiring I would check on OEM options or you can have a hitch fabricated locally and use # C59236 for a 4-way. What will you...
