CURT electrical connectors are designed to give you a reliable connection every time you plug in your trailer. This dual-output connector is designed to be a perfect OEM replacement, plugging into a USCAR socket and supplying power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It is intended to be a replacement trailer connector, plugging into any standard USCAR socket and providing a 4-way flat and 7-way RV blade socket (see application info to verify fitment with your vehicle). It features rust-free black plastic construction and comes with spring-loaded covers to keep out dust and water.
