Replacement OE 7-Way RV Blade Socket (Twists into USCAR)

from

$23.29
Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer’s electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 7-way OEM USCAR replacement connector is designed to plug into a twist-in OEM vehicle socket and supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It features rust-free black plastic construction and comes with a spring-loaded cover to keep out dust and water. This 7-way RV blade connector is a female-end socket, specifically designed for the vehicle side of the connection (see application info to verify fitment with your vehicle).

Product Features:
  • Plugs into USCAR socket to provide 7-way RV blade trailer wiring connector
  • Twist-in, plug-and-play design eliminates the need for cutting or splicing
  • 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power
  • Spring-loaded dust cover keeps connector clean when not in use

CURT – Custom Wiring Connector (4-Way Flat Output; OEM Tow Package Required) (Part No.55441)

Custom Wiring Connector (4-Way Flat Output; OEM Tow Package Required)

from

$23.49
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. Although 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 vehicle’s wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal 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 plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Nissan Frontier, Pathfinder, Xterra and Suzuki Equator (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer — whether you’re 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.

Product Features:
  • Plugs into existing OEM vehicle socket to provide a 4-way flat socket
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Dust cover included to keep connector clean when not in use

CURT – Powered Converter Wiring Kit (10 Amps) (Part No.55151)

Powered Converter Wiring Kit (10 Amps)

from

$20.79
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 converter wiring kit is intended to be used with various CURT powered taillight converters. Powered converters require a direct connection to the vehicle’s battery, and the powered converter wiring kit #55151 provides all of the components needed to establish a secure connection. The kit includes 20 feet of 12 gauge wire, a 10-amp fuse, an in-line fuse holder, a 3/8″ ring terminal, a butt connector, a 14-1/2″ cable tie and eight 6″ cable ties. This wiring kit is rated at 10 amps and comes included with CURT powered electrical converters #59146, #59187, #59190, #59200 and #59201.

Product Features:
  • Routes power from vehicle battery to powered converter
  • Designed for use with battery-powered electrical converters
  • 20′ of 12 gauge cross-linked wire for flexible installation
