This 4‑way to 7‑way trailer‑wiring adapter provides a secure, reliable connection between your vehicle and trailer by converting a standard 4‑way flat vehicle socket to a 7‑way blade trailer connector. Designed for smooth power transfer across 6 to 24 Volts, it supports essential trailer functions including turn signals, brakes, reverse lights, and auxiliary power. The adapter is built from heavy‑duty, rust‑resistant black plastic and features a well‑sealed, spring‑loaded front cover that protects the connection from dust, moisture, and debris. Ideal for trailers, semitrailers, caravans, and RVs, it pairs seamlessly with T‑connectors or tail‑lamp converters using 4‑way flat vehicle ends. Material: Nylon.
