Oyviny 4-Way & 7-Way Trailer Wiring Harness for Nissan Frontier 2005–2025 — Plug-In, Corrosion-Resistant

Oyviny's 4-way and 7-way trailer wiring harness gives compatible Nissan Frontier, Xterra, and Suzuki Equator trucks a factory-style trailer connector without cutting or splicing.

If your vehicle has the factory tow package, this plug-and-play harness adds both a 4‑pin flat and a 7‑pin RV-style socket so you can hook up standard utility trailers and trailers that need brake or auxiliary power. The kit is built from corrosion-resistant materials and comes with a mounting bracket and hardware for a tidy, OEM-like installation. It suits Nissan Frontier models from 2005–2025, Nissan Xterra 2005–2015, and Suzuki Equator 2009–2012.

How simple is the installation?

Installation is designed to be straightforward: the harness plugs directly into the vehicle's factory tow connector—no wire cutting or splicing required. Included mounting hardware helps secure the socket for a finished look that matches the vehicle.

• Plug-and-play design — connects to factory tow package
• Includes mounting bracket and screws
• No trimming or wiring modifications needed
• Hardware and instructions included for a clean fit

Which vehicles and towing setups is this compatible with?

This harness is made for Nissan Frontier (2005–2025), Nissan Xterra (2005–2015), and Suzuki Equator (2009–2012) that already have the factory tow package. It provides both 4‑pin and 7‑pin outputs to support simple light/brake wiring or trailers requiring electric brakes and auxiliary circuits.

• Compatible models listed above only when factory tow package present
• 4‑pin flat for standard trailer lights and signals
• 7‑pin RV-style for brakes, reverse, and auxiliary power
• Allows towing multiple trailer types without adapters

What materials and protections does the harness include?

The harness uses durable ABS for the connector housings and high-quality copper conductors wrapped in abrasion-resistant tape. Tin-plated brass terminals and rubber dust covers reduce corrosion and ensure reliable electrical contact over time.

• ABS plastic connector housings resist rust and wear
• Pure copper conductors for consistent current flow
• Tin-plated brass terminals for corrosion resistance
• Rubber dust covers protect terminals from dirt and moisture

Will this affect onboard vehicle electronics or warranty?

The harness is a direct plug-in designed to interface with the vehicle's existing tow wiring without splicing, which minimizes interference risks. Because it connects to the factory tow connector, it’s typically considered a non-invasive accessory; always check your vehicle warranty and dealer advice for specifics.

• Direct connection to factory tow connector reduces modification
• No cutting or splicing lowers likelihood of wiring faults
• Follow vehicle manufacturer guidance regarding aftermarket parts
• Consult dealer if unsure about warranty impacts

Who is this for? This Oyviny harness is intended for Frontier, Xterra, and Equator owners who already have the factory tow package and need a reliable, clean way to add both 4‑pin and 7‑pin trailer connections. It’s a good choice for drivers who tow varied trailers—from basic utility trailers to boats and campers that require auxiliary power or electric brakes—and prefer a plug‑and‑play, corrosion-resistant solution that installs with factory-style fit and finish.
