56130 3-to-2-Wire Taillight Converter Non-Powered
1 of 4

When your vehicle does not readily provide an electrical connection for hooking up your trailer and there is no factory quick connect harness, CURT electrical converts offer the solution. Working tail lights on your trailer are absolutely essential any time you tow and a converter provides an effective way to properly equip your vehicle for safe towing.

A CURT electrical converter works much like our custom vehicle-to-trailer wiring harnesses and provides a trailer connector on your vehicle by splicing into the vehicle's electrical system. Electrical converters are designed to splice directly into the taillight wiring rather than plugging into various sockets giving them the nickname "taillight converters". Though it requires a little extra work compared to a custom wiring harness, a tail light converter offers a reliable and long-term connector solution.

This CURT electrical converter is designed to convert a 3-wire system to a 2-wire system and provides a standard 4-way flat connector socket to plug in your trailer. This converter is made with cutting-edge surface-mount technology (SMT) circuitry featuring electrical components that are mounted directly to the surface of the board rather than being inserted into a series of holes. SMT circuits have longer life cycles with lower resistance and reduced heat generation and are more reliable than through-hole-mounted components.

  • Converts 3-wire vehicle electrical system to standard 2-wire trailer wiring
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Constructed with SMT circuitry for better performance and durability
  • Color-coded wires for easier installation
  • Snap locks included for fast, secure splicing
  • No heavy-duty flasher or direct battery connection required
  • Dust cover included to keep connector clean when not in use
  • Taillight circuit 5.0 Amps Per Circuit
  • Turn and Brake circuit 3.0 Amps Per Circuit
Note: electrical items are non returnable.
