Built with 18 AWG wires, tin-plated terminals, and a weather-resistant PU sheath, the harness is intended for any trailer system using a standard 4-way plug — including boat, horse, and utility trailers. The coiled design keeps the cable tidy while allowing extra reach for tight turns and offset hitches.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this coiled extension improve trailer maneuvering?\u003c\/h3\u003e\n\u003cp\u003eThe coil stretches during turns so the cable doesn't drag on the ground or get pinched between vehicle and trailer. After a turn it springs back toward the tow vehicle, reducing risk of snags and road wear. This flexibility helps maintain clean, consistent lighting and signal connections while towing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e5-foot coiled length extends when needed and retracts when idle\u003c\/li\u003e\n  \u003cli\u003eReduces cable dragging and tangling on tight turns\u003c\/li\u003e\n  \u003cli\u003eMaintains neat cable routing behind the hitch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this work with my existing 4-way trailer plug?\u003c\/h3\u003e\n\u003cp\u003eYes — the Oyviny extension uses a standard 4-pin male and female connector designed to mate directly with industry-standard 4-way sockets. It’s ready to use out of the box, no cutting or splicing required. Side tabs on the connectors improve grip when plugging or unplugging in wet or cold conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard 4-pin male\/female pair for universal compatibility\u003c\/li\u003e\n  \u003cli\u003eTabs on connectors for easier handling and secure fit\u003c\/li\u003e\n  \u003cli\u003eRubber dust cover keeps mating surfaces clean when disconnected\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow durable and weatherproof is the wiring?\u003c\/h3\u003e\n\u003cp\u003eThe cable combines 18 AWG fully jacketed copper wires, tin-plated brass terminals, and a high-temperature-resistant PU outer sheath for abrasion and weather resistance. That construction resists moisture, road grime, and temperature variation better than unprotected cables. The included rubber dust cover also helps keep corrosion off the connector pins when not in use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePure copper conductors for consistent electrical performance\u003c\/li\u003e\n  \u003cli\u003eTin-plated brass terminals resist corrosion and improve conductivity\u003c\/li\u003e\n  \u003cli\u003ePU sheath withstands wear, UV exposure, and temperature swings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat length should I expect and how stretchy is it?\u003c\/h3\u003e\n\u003cp\u003eThe coiled harness is designed with a 5-foot (60-inch) maximum stretch; in normal use the working length is typically about 40 inches when connected. The spring-back coil preserves cable memory so it remains compact when not stretched. Confirm your required reach before purchase if you need greater than the designed expansion.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned stretch length: 5 feet (60 inches)\u003c\/li\u003e\n  \u003cli\u003eTypical working length around 40 inches under normal towing geometry\u003c\/li\u003e\n  \u003cli\u003eCoil keeps cable compact and reduces excess slack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This Oyviny 4-way coiled extension is made for drivers who tow small to medium trailers and want a tidy, durable, plug-and-play wiring solution. It’s a practical choice for boat owners, horse trailer operators, landscapers, and anyone using a standard 4-pin trailer connection who needs extra reach during turns without running long loose cable. Choose this harness if you need reliable lighting signals, corrosion protection at the connector, and a compact cable that resists dragging.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the Oyviny 4-way extension plug-and-play?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
