- Stress is the last thing you should feel when towing a trailer -- whether youre hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it. CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Though this special socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicles wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular connector provides a 5-way flat socket while retaining use of the existing OEM 7-way. It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). It comes with a dust cover to keep the connector socket clean when not in use.

- A CURT custom original equipment vehicle-to-trailer connector (sometimes called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURTs OE vehicle-to-trailer connectors come into play. A custom wiring connector uses a single original equipment plug to plug into a special socket provided by your vehicle. Though this option is not available on every vehicle, some automotive manufacturers design their vehicles to be easily equipped for towing by supplying a socket, integrated into the vehicles electrical system, to readily accept a custom wiring connector. With a CURT custom OE connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom vehicle-to-trailer wiring connector provides a multi-function connector socket. It is designed to plug into a circular 7-prong OEM socket and replace a factory-equipped 7-way connector with a 7-way RV blade and 4-way flat. It specifically offers a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle).This multipurpose socket comes with its own backup alarm, a mounting bracket and all necessary mounting hardware for a complete installation. CURT custom vehicle-to-trailer wiring connectors are designed to be long-lasting and simple to install. They come with dust covers to keep your connector clean when not in use.

- 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.

They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers, and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Audi Q5 (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 5,000 lbs. GTW and 750 lbs. TW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile, or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2 in. receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping, and UV damage.

- However you define adventure -- whether its climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Audi A4, A4 Allroad, A4 Quattro, A5 Quattro and A5 Sportback (to verify vehicle compatibility, see the CURT application guide at curtmfg.com).

They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid Bonderite, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.
