In this review the Nilight 4 Pin Trailer Wiring Harness Kit is evaluated for owners of mid-2000s to recent Nissan trucks and related models who need a reliable, vehicle-specific 4-way connector. The bottom line: this is a straightforward, OEM-compatible plug-and-play harness that removes the guesswork from adding a standard 4-flat trailer connection. For someone who wants a clean, no-cut installation and a dust cover to protect the connector, this harness delivers the practical towing functionality without extra wiring hassle.

Key Features

• Vehicle-Specific Fit: Designed to plug into factory wiring on 2005-2025 Nissan Frontier, 2005-2015 Nissan Xterra, 2005-2012 Nissan Pathfinder and 2009-2012 Suzuki Equator, which reduces fitment troubleshooting.
• Standard 4-Way Connector: Provides tail light, brake and turn signal wiring in a familiar 4-flat format for use with common trailers and tow accessories.
• OEM-Compatible Connectors: Uses factory-style plugs that attach to the vehicle harness behind the center of the rear bumper, keeping the installation clean and reversible.
• Plug-and-Play Installation: No cutting or splicing of factory wire is required, so the harness is suitable for owners who prefer a simple DIY install or quick shop fitting.
• Protective Dust Cover: A tight-fitting rubber cap comes with the kit to keep the connector protected from moisture and road grime when not in use.
• Complete Kit Contents: The package includes the custom 4-pin harness, six zip ties and one screw to secure and finish the installation neatly.

Who It's For

This harness is best for owners of Nissan Frontier, Xterra, Pathfinder and compatible Suzuki Equator models listed who need a reliable, factory-compatible 4-way trailer connector without modifying vehicle wiring. It suits DIYers and professional installers who value a plug-in solution and want a connector that stows near the hitch.

It is less appropriate for users who need a 7-way round connector, power feed for trailer brakes or custom wiring beyond basic lighting. Buyers who require additional trailer power circuits or integrated brake controllers should look for a different harness or adapter.

Pros & Cons

Pros

• Vehicle-specific OEM-style plugs make installation fast and minimize compatibility issues.
• Standard 4-flat connector supports tail, brake and turn signals for common trailer types.
• Included dust cover and mounting hardware help protect the connector and keep the install tidy.

Cons

• Only provides a 4-way connection, so it does not supply auxiliary power or a brake controller feed for trailers that need additional circuits.
