Description

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. This 7-way RV blade replacement harness is designed to replace an existing 7-way plug on your trailer and supply 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 features color-coded wires for easy splicing into your trailer's wiring system. With a 10' cable and protective plastic sleeve, this harness is perfect for RV travel trailers, providing more than enough length to accommodate virtually any vehicle-trailer combination and maintaining a solid electrical connection in spite of the elements. This 7-way RV blade connector is a male-end plug, specifically designed for the trailer side of the connection.

Key Features

EASY GRIP. Plugging in your trailer wiring and trailer lights is easy with the ergonomic design of this trailer plug. It features two hooks on either side of the plug for a better grip when plugging in or unplugging trailer wiring

WEATHER-RESISTANT. This trailer wiring plug comes with concealed wire terminals. This helps protect the splice-in connection points for the wires, keeping them safe from dirt, rain, corrosion and other threats

RELIABLE CONNECTION. This 7-pin trailer wiring plug comes ready to splice into your existing trailer wiring. It can be used to connect the taillights, brake lights, reverse lights, turn signals, trailer brakes and auxiliary power

VERSATILE DESIGN. This connector makes a great replacement 7-way RV blade harness and is interchangeable with virtually any 7-way RV connector. 7-pin trailer wiring is commonly used on RV travel trailers

READY TO INSTALL. Equipped with blunt-cut, color-coded wires, this 7-pin trailer wiring plug comes ready to install. The 10-foot wire lead provides plenty of extra length for an easy installation
