"Curt Custom 4 Flat Connector
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.

CURT Trailer Brake Controller Wiring Kit
It takes a lot of power to stop a moving trailer, especially when that trailer is hauling livestock, construction materials, industrial equipment or other heavy-duty cargo. Play it safe when you tow and give your trailer brakes the control they need with a CURT trailer brake controller and brake controller harness. This brake controller wiring kit is designed for vehicles that do not have an included towing prep package. It includes cables, ring terminals, cable ties and a circuit breaker to splice into your vehicle's wiring system and allow installation of a CURT trailer brake controller. This wiring kit is compatible with systems with up to eight brakes.
  • Trailer Brake Controller Wiring Kit
  • For tow vehicles not equipped with factory tow package wiring
  • Compatible with 2, 4, 6 or 8-brake systems (1-4 axles)
  • Designed for use with CURT quick plugs #51515 or #51516
  • Brake controller and trailer connector are not included
