Oyviny 4 Way Flat Trailer Wiring Harness for Nissan

Oyviny 4 Way Flat Trailer Wiring Harness connects your Nissan Frontier, Xterra, or Suzuki Equator factory tow package to a standard 4‑pin trailer plug for reliable turn, brake, and running lights.

If your Nissan Frontier (2005–2025), Nissan Xterra (2005–2015), or Suzuki Equator (2009–2012) has a factory tow package and you need a direct replacement for a damaged or worn trailer wiring harness, this Oyviny plug‑and‑play assembly restores trailer lighting quickly. It provides a standard 4‑pin flat connector with corrosion‑resistant terminals, a rubber dust cover, and a protective nylon loom for long service life. Note: vehicles without the factory tow package will need the vehicle’s running light relays or dealer modules to enable trailer running lights.

How does this harness restore trailer lighting on my Nissan or Suzuki?

The harness plugs directly into the vehicle’s factory tow connector, matching the OEM pin layout for turn, brake and tail lights. No cutting or splicing is required when your vehicle already has the tow package wiring in place.

• Direct plug‑in connector matches factory harness pins
• Provides brake, turn and running light circuits via 4‑pin flat
• 70‑inch cable length for flexible routing behind bumper
• Rubber dust cap protects the socket when unused

Will this harness work with my specific model year?

This Oyviny harness is designed for compatibility with Nissan Frontier model years 2005–2025, Nissan Xterra 2005–2015, and Suzuki Equator 2009–2012 as long as the vehicle has the factory tow package. Confirm your vehicle has the tow package connector before purchasing.

• Frontier: 2005–2025 support list
• Xterra: compatible for 2005–2015 models
• Equator: fits 2009–2012 models with factory tow package
• Not a converter—requires existing tow wiring in vehicle

What materials and protections ensure long life for the harness?

The wiring is bundled in a black nylon loom to resist abrasion and keep the assembly neat during installation and use. The connector uses tin‑plated copper terminals and a corrosion‑resistant housing to maintain electrical contact over time.

• Nylon wire loom for abrasion resistance and bundling
• Tin‑plated copper terminals for consistent conductivity
• Corrosion‑resistant 4‑pin plug with easy‑grip body
• Rubber dust cover protects contacts from moisture and dirt

How easy is installation and what tools are needed?

Installation is simple for vehicles equipped with the factory tow connector: align and insert the OEM mating plug, secure routing with existing clips, and fasten any ground if required by your vehicle design. No splicing, soldering, or wire modification is necessary for a direct replacement.

• Plug‑and‑play: connects to factory tow harness without cutting
• 70" cable gives room to route behind bumper and frame
• Minor hand tools may be needed to remove access panels or clips
• If vehicle lacks tow package, dealer relays/modules are required for running lights

Who is this for: The Oyviny 4 Way Flat Trailer Wiring Harness is aimed at Nissan Frontier, Xterra, and Suzuki Equator owners who already have a factory tow package and need a reliable OEM‑style replacement harness. It’s ideal for DIYers wanting a fast plug‑in swap, fleet managers maintaining multiple trucks, or anyone replacing a corroded or damaged connector without altering vehicle wiring. If your vehicle lacks the tow package or you need converters for additional circuits, consider a relay kit or multi‑pin harness instead.
