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 7-way RV blade socket and comes with quality plastic construction. For any and all-types of trailers with electric trailer brakes, a Curt breakaway kit provides you with the equipment you need to be prepared. We offers three different complete breakaway systems to accommodate various trailer sizes and meet your specific towing needs. All of our breakaway kits are tested for your safety and meet DOT requirements for holding and breakaway situations. This breakaway switch offers reliable activation of your trailer brakes, featuring silver contact points for a solid connection and a nylon case to protect against the elements. It is designed for use with the Curt Soft-Trac 1 and Soft-Trac 2-breakaway kits and features a high-temp wieldable tab for convenient mounting. Nobody hitches up a trailer expecting a breakaway, but that doesn't mean you should tow unprepared. Be ready for anything with a Curt breakaway kit.

Curt 57020 Dual-Output Connector Plug, 12 V, Black Your Price: $39.99 Curt 55774 Connector Your Price: $44.99 Curt 56070 Custom Wiring Harness Extension, 7 ft L Your Price: $87.99 A curt connector provides a reliable connection for your trailer wiring, using an industry-standard format, such as a 4-way flat, 6-way round or 7-way RV blade. They can be used to install new wiring on a vehicle or trailer or as replacement connectors for existing wiring. This particular connector is designed to be a ideal OEM replacement, providing a 4-way flat socket and 7-way RV blade socket to accept either trailer plug type. It features a USCAR base to connect to a standard USCAR plug (see application info to verify fitment with your vehicle). Once plugged into the USCAR socket, it provides a connection for the taillights, turn signals, brake lights, backup or reverse lights, electric trailer brakes and a 12 V battery. It also provides a connection for the ground wire. This trailer wiring connector is built to withstand the elements. It is constructed from durable black molded plastic to be impervious to rust, and it features spring-loaded dust caps to keep out rain, salt, grime and dirt when the connectors are not in use. 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 USCAR connector and offers a four-way flat and six-way round connector (see application info to verify fitment with your vehicle). It also comes with a mounting bracket for easy installation. 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. There is nothing like the luxury and power that go along with heavy-duty towing. Fifth wheel RV's offer a deluxe, home away from home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, fifth wheels and goosenecks must be equipped with the proper lighting and electrical systems and tend to require even more complex connectors than a standard receiver type trailer setup. Make things simple with a Curt fifth wheel or gooseneck extension harness. These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your fifth wheel or gooseneck trailer. This Curt extension harness is designed to work with seven way RV blade connectors and comes in a length of 7 ft. When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, Curt gets you plugged in. 1
