Oyviny 7-Way Round to 5-Way Flat Trailer Plug Adapter — 5 ft Coiled Cable, Brass Terminals

The Oyviny 7-way round to 5-way flat coiled trailer plug adapter converts a vehicle’s 7-pin blade connector into a 5-pin flat trailer connection with a flexible 5-foot coiled cable for reliable towing hookups.

When you need to tow trailers, campers, or utility loads that use different wiring standards, this compact adapter removes the hassle of multiple cables or rewiring. Built with brass terminals and pure copper conductors, the adapter transfers power for running lights, turn/brake signals, ground and reverse lights. Its coiled design stores neatly and stretches as needed for tight turns, while a simple plug-and-play setup means no splicing or complex installation.

How does this adapter handle different trailer wiring setups?

The Oyviny adapter translates the common 7-pin blade (round) vehicle socket to a 5-pin flat trailer plug, so your vehicle can communicate with trailers that only require five circuits. It preserves the core light and signal functions and keeps wiring separate without altering either socket.

• Converts 7-pin blade to 5-pin flat wiring standard
• Supports ground, running lights, left/right turn and reverse lights
• No cutting or splicing—plug-and-play connection
• Brass terminals and pure copper wiring for steady conductivity

Will the coiled cable reach during tight turns and towing maneuvers?

The coiled construction lets the cable retract for tidy storage and extend when you need additional length while turning. Although the product’s full stretched length is listed as 5 feet (60 inches), typical usable stretch under towing conditions is closer to 36 inches—plan your setup accordingly.

• Coil design prevents dragging and tangling behind the vehicle
• Elastic memory keeps cable compact when not in use
• Stretchable to provide extra slack for close turns
• Weather-resistant insulation for regular outdoor use

How durable and conductive is the wiring and connector hardware?

Oyviny engineered the adapter for dependable electrical contact and daily towing wear. The terminals are metal (brass) and wires are copper, which together lower resistance and help consistent signal transfer for lights and indicators.

• Brass contact pins resist corrosion and maintain tight fit
• Pure copper conductors for efficient current flow
• Rugged connector housings to withstand frequent plugging cycles
• Built to simplify connections without altering factory wiring

How easy is it to install and use this adapter?

Installation is straightforward: align the 7-pin blade socket to your vehicle and plug the 5-pin flat into the trailer receptacle. No tools or wire splicing are necessary, and the adapter includes easy-grip hooks for a firmer hold when connecting or removing the plug.

• Ready to use out of the box—no electrical work required
• 2 handle hooks on the 7-way socket for improved grip
• Compact coiled cable stores neatly when disconnected
• Works with standard 7-pin vehicle sockets and 5-pin trailers

Who this is for: The Oyviny 7-to-5 coiled adapter is made for drivers who tow multiple trailers or occasionally hook up a trailer with a different connector type. It’s ideal for RV owners, landscapers, weekend boaters, or anyone who needs a quick, reliable way to convert a 7-pin vehicle outlet to a 5-pin trailer connection without rewiring. If you need a compact, conductive, plug-and-play solution that keeps cables tidy and gives a little extra length during turns, this adapter meets those needs—just confirm the effective stretched length fits your towing configuration before purchasing.
