Oyviny 4-Pin Trailer Wiring Harness 55329 for Dodge Ram 1995-2002 & Dakota 1995-2003 | Factory Tow Package Required

Oyviny Custom 4-Pin Trailer Wiring Harness 55329

The Oyviny 4-pin trailer wiring harness is crafted for Dodge Ram 1995–2002 (1500/2500/3500) and Dodge Dakota 1995–2003 models that include a Factory Tow Package. This connector creates a straightforward path for trailer lighting signals, helping your trailer’s tail lights, brake lights, and turn signals synchronize with the vehicle’s system. A key note: ensure your vehicle is equipped with a Factory Tow Package, otherwise the plug may not fit the harness socket.

Real-world benefits for everyday towing

When you’re on the road, reliable trailer lighting matters for safety and visibility. The Oyviny harness is designed to maintain consistent signaling across a range of trailer types, supporting smoother when-lights-are-needed communication between your tow vehicle and the trailer. The result is a practical upgrade that can enhance confidence during weekend trips, cargo runs, and camp-site setups.

Installation simplicity you can feel

• Black nylon net tube shielding guards the harness from weather exposure and abrasion.

Durability meets daily use

• Rugged construction stands up to road grime, moisture, and temperature changes.
• Corrosion-resistant materials help maintain a clean electrical path over time.
• Protective casing and weather protection contribute to longer service life in varying climates.

Versatility for a wide range of trailers

Care, use, and best practices

Follow the vehicle’s load ratings and the product’s limits to avoid overloading circuits. Store the harness where it’s dry and free from sharp edges when not in use to preserve connector integrity over time.
