Oyviny 7-Pin Round to 7-Pin RV Blade Adapter — 14in Lead with Mounting Bracket, Weather-Resistant

The Oyviny 7-pin round to 7-pin blade adapter converts a vehicle's 7-way round outlet to a standard 7-way RV blade connector with a 14-inch lead and included mounting bracket.

This compact adapter makes connecting a tow vehicle to an RV-style trailer fast and secure when the vehicle uses a combined brake/turn signal circuit. Built with a molded plug, weather-resistant dust cover, and a protective nylon wire loom, the Oyviny adapter is designed for reliable seasonal and everyday towing. It includes a mounting bracket and hardware so you can fix the adapter near the hitch for tidy storage and quick hookups.

How does this adapter fit different vehicle and trailer plugs?

The adapter converts a 7-way round vehicle socket to a 7-way blade trailer plug, matching common RV wiring standards. It is intended for vehicles where brake lights and turn signals share circuits; it will not function correctly on trucks or tractors that use separate brake circuits.

• 7-way round (vehicle side) to 7-way blade (trailer side) electrical conversion
• 14-inch cable length for flexible placement around the hitch
• Not compatible with vehicles that separate brake and turn signals (some trucks/semis)
• Suggested pin testing before towing to confirm function

What protection and durability features does the Oyviny adapter provide?

The adapter is built for outdoor use with a molded plug that resists weather plus a spring-loaded dust cover that shields terminals when not connected. A black nylon wire loom bundles and protects the conductors against abrasion and road debris, extending service life.

• Molded 7-way plug resists cracking and moisture intrusion
• Spring-loaded dust cover protects pins from dirt and corrosion
• Nylon wire loom prevents chafing and wear at the harness
• Rugged materials suitable for repeated hookups and storage

How easy is installation and where does the mounting bracket help?

Installation is plug-and-play: simply connect the round plug to the vehicle and the blade end to the trailer plug. The included mounting bracket and fasteners allow you to secure the adapter near the hitch so it’s always accessible and won’t drag or dangle while driving.

• Plug-and-play connections require no splicing for compatible vehicles
• Mounting bracket keeps the adapter off the ground and organized
• All installation hardware included for immediate mounting
• 14-inch lead provides room to position the bracket for neat routing

What should I check before using this adapter?

Because 7-pin wiring can vary, verify each pin’s function with a trailer light tester or multimeter before towing. Some vehicles may require swapping pins in the adapter to match bespoke wiring; this prevents incorrect signal routing and unsafe lighting behavior.

• Use a tester to confirm pin assignments on both vehicle and trailer
• Be aware some commercial trucks separate brake and turn signals
• Swap pins if necessary or consult an electrician for custom wiring
• Inspect the dust cover and loom regularly for damage

Who is this for: The Oyviny adapter is made for owners of passenger vehicles, SUVs, and light-duty trucks that use a combined brake/turn signal 7-way round socket and who tow RV-style trailers, campers, or utility trailers with a 7-way blade connector. It’s also a good choice for DIYers who want a durable, weather-resistant adapter with a mounting bracket for tidy storage and fast hookup.
