One end uses a male 7-way RV blade plug that connects to the vehicle-side socket, while the opposite end provides a female 7-way RV blade socket for the trailer-side plug. The 4-foot length gives practical slack for extended hitches, tight turns, long tongues, and specialized mounting locations while helping avoid excess cable dragging near the road surface.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"rp-card rp-service\"\u003e\n        \u003ch2\u003eR\u0026amp;P Service Insight\u003c\/h2\u003e\n        \u003cp\u003eA 7-way extension cord is often used when the trailer plug cannot comfortably reach the tow vehicle socket.
