Nilight 4-Flat Trailer Wiring Harness for Dodge Durango 2014–2025 — Plug-and-Play OEM Fit with 4-Pin Socket and Dust Cover

Nilight 4 Pin Trailer Wiring Harness Kit 56336 is a vehicle-specific, plug-and-play 4-flat connector that gives 2014–2025 Dodge Durango owners a fast, OEM-compatible way to power trailer tail, brake, and turn lights without cutting factory wiring.

This harness is built to fit behind the taillight housings of Dodge Durango models from 2014 through 2025 and converts the factory wiring into a standard 4-way trailer outlet. The kit includes everything needed for a neat installation: the custom harness, zip ties, a mounting screw, a 10A fuse, and extra wire to route the connector to the hitch. Weather protection is provided by a snug rubber dust cover so the socket stays clean when it’s not in use.

How does the Nilight harness connect to my Durango's wiring?

The harness uses vehicle-specific OEM-style plugs designed to mate with the factory wiring behind the driver and passenger taillight housings. There’s no need to cut, splice, or modify factory wires; the harness simply plugs in to tap the taillight, brake, and turn signal circuits.

• OEM-compatible connector pairs to factory sockets behind taillights
• Plug-and-play installation with no permanent wire changes
• Includes 10A fuse to protect the trailer circuit

Will this provide the standard 4-way trailer functions I need?

Yes — the Nilight 56336 delivers the universal 4-flat wiring standard: running lights, left and right turn/brake signals, and a shared ground. That compatibility lets you hook up most small trailers, cargo carriers, and light-duty towing accessories without adapters.

• 4-flat connector supplies running, brake, and turn signals
• Common ground built into the plug for reliable light function
• Connector stores beneath the vehicle near the hitch when not in use

How durable is the kit for outdoor and towing use?

The kit is designed with outdoor durability in mind: the 4-way socket is paired with a rubber dust cover to keep out dirt, moisture, and road debris when unused. The harness wiring and terminals are suited for normal towing conditions and mounted to the vehicle with supplied zip ties and hardware for secure routing.

• Tight-fitting rubber dust cover protects the connector from weather
• Durable jacketed wiring resists road abrasion when routed properly
• Zip ties and screw included for neat, secure attachment points

How long does installation take and what tools are needed?

Most DIYers can complete installation in under an hour with basic hand tools. The plug-and-play design removes the need for wire strippers or crimping; you'll route the included cable from the taillight area to the hitch, secure it, and plug it into the factory sockets.

• Typical install time: 30–60 minutes depending on experience
• Basic tools: socket set or screwdriver for the screw, trimming tool for minor routing if needed
• All fastening supplies included: nine zip ties and one screw

Who is this for: The Nilight 4 Pin Trailer Wiring Harness Kit 56336 is intended for Dodge Durango owners (model years 2014–2025) who want a clean, reversible, OEM-style solution to add a standard 4-way trailer connector. It’s ideal for weekend haulers, cargo carriers, small boat trailers, and anyone who wants a weather-protected, reliable trailer outlet without altering factory wiring.
