CURT – Multi-Function Taillight Converter (Part No.56236)

Multi-Function Taillight Converter

from

$99.99
Rain, road grime and salt can deal a vicious blow to your trailer wiring, and it takes electrical components with an extra-thick shell to stand up to the elements. The CURT multi-function electrical converter is an advanced taillight converter that offers the ultimate in vehicle compatibility and weather resistance, giving you a reliable wiring connection any season of the year. The potted design seals the internal electrical components in a watertight enclosure and is filled with a solid compound to protect against impacts, vibrations and moisture for long-lasting use, even on the exterior of the vehicle. The converter also features our advanced surface mount technology (SMT), using smaller components mounted directly to the surface of the circuit board. This produces lower resistance, reduced heat generation, longer life cycles and higher reliability. The CURT multi-function electrical converter comes with pigtail wires that are able to be spliced into two-wire, three-wire or PWM wiring system with combined stop and taillights. It converts any of these systems to a simple two-wire system, using a standard 4-way flat output, to be compatible with most trailer wiring. The converter is controlled using a microcontroller that is able to sense the current passing through it, allowing for quick reaction to dangerous conditions such as overload and short circuits. It also filters unwanted input signals to protect your wiring systems and uses a mere seven volts for low-voltage operation. The CURT multi-function taillight converter is a heavy-duty electrical converter for virtually any vehicle-trailer combination. It comes with color-coded wires and an easy-to-read wiring guide, as well as a dust cover to protect the 4-way flat connector. This package also includes four snap locks for faster, more secure splicing. A powered converter wiring kit #55152 is also required for installation.

Product Features:
  • Converts 2-wire, 3-wire or PWM ST system to 2-wire trailer light wiring
  • Potted enclosure significantly increases water and vibration resistance
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Constructed with SMT circuitry for better performance and durability
  • Microcontroller senses current to rapidly react to overload
  • Provides improved overload, short-circuit and thermal protection
  • Low-voltage operation allows function down to seven volts
  • Color-coded wires with wiring guide for easier installation
  • Snap locks included for fast, secure splicing
  • Dust cover included to keep connector clean when not in use

CURT – Powered 3-to-2-Wire Taillight Converter (Part No.56190)

Powered 3-to-2-Wire Taillight Converter

from

$62.99
When your vehicle does not readily provide an electrical connection for hooking up your trailer, 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, much like our custom vehicle-to-trailer wiring harnesses, provides a trailer connector on your vehicle by slicing 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, 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. It is designed to fit certain years of the Audi Q5 (except hybrid), BMW 328i xDrive sedan, BMW X5 SUV, Infiniti M37x sedan or Mercedes SLK250 (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com).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, lower resistance, reduced heat generation and are more reliable than through-hole-mounted components.

Product Features:
  • 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 required
  • Dust cover included to keep connector clean when not in use
