  • EASY GRIP. Plugging in your trailer wiring and trailer lights is easy with the ergonomic design of these trailer wiring connectors. The trailer plug features tabs on the sides for a better grip when plugging into the vehicle socket or unplugging
  • VERSATILE DESIGN. These trailer wiring connectors make great replacement 4-flat wiring plugs and socket. They match industry-standard 4-way round connectors and connects the taillights, brake lights and turn signals
  • DURABLE CONSTRUCTION. For long-lasting use and a reliable connection, the housing of these 4-pin trailer wiring connectors is made from strong, durable die-cast metal
  • RELIABLE CONNECTION. These 4-way round trailer wiring connectors are equipped with locking tabs that secure the plug into the socket when inserted. This helps maintain a reliable wiring connection in spite of bumps and vibrations while towing
  • WEATHER-RESISTANT. To help protect the splice-in wiring connections, these 4-wire trailer plugs feature concealed terminals, keeping the wires from direct exposure to rain, dirt, road salt and other corrosive threats (wires not included)


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. These 4-way round connectors are designed to supply power for tail lights, turn signals and brake lights, as well as a ground connection. They feature durable die-cast metal construction and come with concealed terminals and a spring-loaded steel cover to resist damage from dust and water. This 4-way round connector kit includes both a male-end plug for your trailer and a female-end socket for your vehicle.

I needed this as a replacement and assumed this type of connector was a standard size. The quality of the plug and socket are very nice, however it was significantly larger than the existing one and would not fit my application unfortunately. Still recommend though!

It was small in size and worked just great where I needed it. I use it to connect pick up wiring to a camper For a quick disconnect when removing camper

Absolutely no complaints about this item or its construction/durability. But beware - I have two vehicles all wired with the same item, but a different brand, and needed to add ONE MORE connector. Got everything ready to go and discovered the external plug WILL NOT fit the previous connectors. OD on this is 7/8 inch. My previous installations are 3/4 inch, so I'm back to trying to find one that will fit. Unfortunately, I have yet to find one that shows the OD of the external piece, and I'm not tearing into my equipment to replace everything to accommodate this item. If you're getting both parts for a new installation, go for it. If trying to replace either piece of another brand, be sure to measure first. I thought they were all the same. Not so.

Prenez note que c’est un 4 fil et non un 7 plus que parfait pour le prix!

If this had cost 5 times more than it is then there would be some small design complaints and the fit and finish isn't perfect, but for the price is an incredible product, highly recommend
