Oyviny Truck Bed 7-Pin Wiring Extension – 7.5 ft Universal Gooseneck/Fifth-Wheel Harness

Upgrade your trailer wiring with the Oyviny Truck Bed 7-Pin Wiring Extension. This durable, 7.5-foot harness adds a secondary 7-way outlet in the truck bed, enabling safer and more versatile towing for gooseneck and fifth-wheel configurations without overhauling your existing setup.

Why this extension makes sense

Built to work with a broad range of pickups and trailers, this kit preserves the factory 7-way RV socket while delivering an additional outlet for taillights, brake lights, reverse lights, turn signals, trailer brakes, and auxiliary power. The 7.5-foot run provides ample slack to route the wiring cleanly along the bed, keeping the cab area uncluttered and reducing strain on connections during travel.

Durability is a core focus. The wiring uses bonded copper conductors in 10 AWG / 12 AWG / 16 AWG gauges for strength and reliable conductivity, while high-strength ABS connectors stand up to weather and road wear. A spring-loaded dust cover shields the connector from dust and moisture, helping it stand up to regular outdoor use. The included heavy-duty wire loom protects the run from abrasion and bending, so you can tow through varying terrains with confidence.

Plug-and-play installation you can trust

The design emphasizes simplicity: plug directly into your factory wiring harness adapter—no cutting or splicing required. The kit arrives with zip ties and screws to securely mount the harness along the truck bed, delivering a tidy, professional finish without special tools or expertise.
