CURT – Dual-Output 7/4-Way Connector (Plugs into USCAR) (Part No.55774)

Dual-Output 7/4-Way Connector (Plugs into USCAR)

from

$31.49
A CURT custom wiring 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 CURT’s custom wiring 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 vehicle’s electrical system, to readily accept a custom wiring connector. With a CURT custom wiring connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom wiring connector actually provides two connector sockets for a multipurpose option. It plugs into an OEM connector and offers a 4-way flat and 7-way RV blade connector. It comes with a mounting bracket for easy installation and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment). CURT custom 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.

Product Features:
  • Plugs into USCAR socket to provide 4-way and 7-way trailer wiring connectors
  • Fits USCAR-equipped vehicles with factory tow plugs only
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • 7-way RV blade socket adds reverse lights, electric brakes and auxiliary power
  • Dust covers included to keep connectors clean when not in use
  • Slit loom keeps wires contained and well protected
  • Metal bracket securely mounts wiring to the vehicle or trailer hitch

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
