Extend your trailer wiring with confidence

Whether you're hitching a boat trailer after a day on the water or upgrading a utility trailer for weekend projects, a reliable 4-pin flat wiring extension can simplify connections. Oyviny's 4-Ft Vehicle & Trailer Wiring Harness offers a sturdy, weather-ready link between your tow vehicle and trailer, with a straightforward plug-and-play design. The 4-flat extension supports taillights, brake lights, and turn signals, helping you focus on the road rather than the wiring.

Key benefits

  • 16AWG pure copper wires deliver dependable conductivity for clear power and signal transmission.
  • Color-coded wires simplify identification and installation, reducing the risk of miswiring.
  • Rubber dust covers shield terminals from water and dust when the connectors are unused.
  • Nylon net sleeve protects the cable and resists wear in busy environments.
  • Plug-and-play design means no cutting or splicing is required, saving time and effort.
  • 4-foot length balances reach and manageability for most vehicle-to-trailer layouts.

Practical uses

Picture a sunny day at the marina: you simply connect the extension and verify taillights light up as you prepare to back in. On a weekend build, the extension reaches from a pickup to a utility trailer without improvising splices. For a horse trailer, the familiar four-wire setup helps keep your gear and riders ready for the road.

What you get

  • 4 ft trailer wiring extension with male and female ends
  • Rubber dust covers on both connectors
  • Nylon net sleeve to guard the wires
  • Color-coded 16AWG copper conductors
  • Durable construction suitable for frequent trailer use

Installation tips

  • Plug-and-play: connect the male and female ends to the respective vehicle and trailer wiring.
  • Match the wire functions by color to avoid misconnections.
  • Ensure connections are clean and dry before testing your lights.
  • Test taillights, brake lights, and turn signals before hitting the road.

Note: Results can vary based on vehicle and trailer wiring. This extension is designed to help streamline connections, not guarantee specific outcomes in every setup.
