  • 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 perfect 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-volt 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., OEM REPLACEMENT DUAL-OUTPUT 7 & 4-WAY CONNECTOR (PLUGS INTO USCAR) #57020 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. Easy, snap-in installation. 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. Rubber gasket to keep moisture and elements out. Spring-loaded dust covers keep connectors clean when not in use. Pre-greased terminals for a reliable connection. Backed by a limited one-year warranty.
  • Like our standard replacement 7-way RV blade harnesses, CURT cold-weather harnesses replace the trailer-end of your wiring system and easily splice into the existing trailer wires. However, our cold-resistant harnesses also come with a unique thermoplastic elastomer casing. The casing is made to be soft enough that it will not stiffen in the cold, yet durable enough to provide good protection for the wires within. The harness is rated to remain flexible in temperatures as low as -40°F, allowing you to easily plug in and tow no matter what the season of the year and no matter how far north the road takes you. CURT cold-weather wiring harnesses quickly splice into your existing trailer wiring, using a pigtail end with standard color-coded wires. The 7-way RV blade plug connects taillights, brake lights, reverse lights, turn signals, electric trailer brakes and auxiliary power. Cold-weather wiring harnesses also come in three different lengths, including 6', 8' and 10', to provide the right fit for your trailer and towing setup., COLD-WEATHER REPLACEMENT 7-WAY RV BLADE WITH 6' WIRES (TRAILER SIDE) #56611 Replaces the trailer-end plug of any 7-way harness. Soft thermoplastic elastomer casing remains flexible in cold temperatures. Temperature rating from -40F up to 221F. Interchangeable with other 7-way RV blade connectors. 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power. 6' cord length to fit your specific towing setup. Color-coded wires for easier splicing.

  • 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. This CURT powered taillight 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 advantage of this converter is its potted construction. 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. This CURT taillight converter comes with pigtail wires that are able to be spliced into the three-wire vehicle wiring system and convert it to a simple two-wire system, using a standard 4-way flat output, to be compatible with most trailer wiring.
