Nilight 4 Pin Trailer Wiring Harness for 2021-2024 Ford Bronco Sport

In this review the Nilight 4 Pin Trailer Wiring Harness for the 2021-2024 Ford Bronco Sport is assessed as a straightforward, vehicle-specific solution for drivers who need a standard 4-way connector with minimal fuss. The biggest reason to consider this harness is its plug-and-play design that avoids cutting or splicing factory wiring, making it attractive for DIY owners who want a clean installation and a tucked-away connector near the trailer hitch. Installation simplicity and compatibility with Bronco Sport factory taillight harnesses are the standouts.

Key Features

• Vehicle-specific fit: Designed for 2021-2024 Ford Bronco Sport, the harness uses OEM-compatible connectors to mate with the vehicle wiring behind both taillight housings for a direct fit.
• Standard 4-flat connector: The plug-in 4-way provides tail light, brake and turn signal circuits so common trailers and lighted accessories can be connected without adapters.
• Plug-and-play installation: No cutting or splicing of factory wire is required, which protects the vehicle wiring and reduces installation time for most users.
• Dust cover included: A tight-fitting rubber dust cover protects the 4-way flat connector when not in use, improving weather resistance and longevity.
• Complete kit: The package includes the custom harness, zip ties, a 15A fuse and a screw so users have the basic hardware needed for mounting and routing.

Who It's For

This harness is aimed at Bronco Sport owners who tow light trailers, carry bike racks or need a reliable rear light connection without modifying factory wiring. It suits weekend tow users and DIYers who prefer a tidy, reversible installation and value a connector that stows near the hitch.

It is not intended for heavy commercial towing or for users who require multi-pin functions such as electric brakes or 12V power at the connector. Customers who need advanced trailer features or a different connector type should look for a multi-function wiring solution or a professional install that supports additional circuits.

Pros & Cons
