CURT 58260 Vehicle Socket Way Flat Towing Tester 4-Pin Trailer Wiring

Part of towing responsibly is making sure your trailer lights are working properly. Whether you have just installed a new custom wiring harness or are trying to locate the cause of an electrical problem, CURT connector testers are great for testing tail lights, turn signals, brake lights, ground connections and other electrical components on your vehicle. A connector tester works by plugging into the connector socket on your vehicle and responding to the various electrical signals produced by pushing the brake pedal, signaling a turn, turning on the running lights and so on. When the socket is getting proper power, the tester's various LEDs will light up corresponding to each wire in the connector. Testing your vehicle-side socket is essential after installing a new custom vehicle-to-trailer wiring harness and is highly recommended every time you hitch up to tow. Also, if you are experiencing electrical problems with your trailer, a CURT tester will be able to tell you whether the problem is rooted in your vehicle's electrical system or if your trailer needs some rewiring. All CURT connector testers come with LED lights to be bright and long-lasting. Wire testers are available for 4-way flat, 5-way flat, 6-way round and 7-way RV blade connectors. This particular electrical tester fits a 4-way flat socket and comes with quality plastic construction.

Features

  • VERSATILE. Quickly and confidently confirm the functionality of your vehicle's trailer wiring harness with this connector tester for the taillights, brake lights and turn signals.
  • SIMPLE TO USE. For each electrical function, an LED lights up indicating a good signal. Just plug the wiring tester into your vehicle's socket and have a helper check the LED signals as you activate them from the driver's seat.
  • EASY GRIP. Plugging in this 4-flat trailer light tester into your vehicle is easy with its ergonomic design. It features a tab on the bottom for a better grip when plugging in or unplugging.
  • LONG-LASTING LEDS. To produce a bright, easy-to-read signal and ensure long-lasting use, this vehicle-trailer wiring tester is constructed with LED diodes.

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.

Features

  • VERSATILE DESIGN. This dual-output connector is a great upgrade for a variety of vehicles with a USCAR socket. It provides two standard trailer wiring sockets, a 4-way flat and an RV blade 7-way round socket, allowing for versatile towing options.
  • WEATHER-RESISTANT. This two-way trailer wiring socket is designed to outlast weather exposure. The 7-pin socket has a spring-loaded dust cover that keeps the connection points dry and protected when not in use, and the 4-flat connector has an included dust cap.
  • RELIABLE CONNECTION. These trailer wiring sockets come ready to plug into your existing vehicle wiring, using the factory USCAR socket. They can be used to connect the taillights, brake lights, turn signals, reverse lights, electric trailer brakes and auxiliary power.
  • USCAR-SPECIFIC. This trailer wiring harness socket is designed for specific vehicles with an industry-standard USCAR socket.
