7-Pin Metal Trailer Connector (Female Socket, 12V)

The 7-pin metal trailer socket is designed to provide a reliable electrical connection between your towing vehicle and a trailer or caravan. The sturdy metal housing offers superior durability compared to plastic connectors – it won’t crack and can withstand impact and pressure, which is especially important for off-road towing or heavy-duty use. This socket follows the standard 7-pin (12V) configuration, meaning it supports all necessary light functions (left/right indicators, brake lights, tail/running lights, fog or reverse light, ground, etc.) in accordance with European trailer wiring norms. It is intended for mounting on the towing vehicle (female socket), usually near the tow bar, and will mate with any standard 7-pin trailer plug (male) from the trailer side.

Key features and benefits:

• High durability: The metal body (typically aluminum alloy or zinc die-cast) is corrosion-resistant and weatherproof. This makes it suitable for use in harsh conditions – winter road salt, rain, mud – or with boat trailers where immersion in water can occur. The robust construction ensures a long service life even under frequent towing.
• Spring-loaded cover: The socket includes a spring-hinged lid that automatically closes when the trailer plug is removed. This protects the contacts from dust, moisture, and debris, prolonging the connector’s lifespan and ensuring a good connection every time you plug in the trailer.
• Easy wiring: Inside the socket, each of the 7 pins has a screw or clamp terminal for attaching wires, usually labeled or color-coded according to standard. The standard wiring color code (e.g., yellow – left turn, green – right turn, brown – tail lights, red – brake, blue – fog, white – ground, black – auxiliary) helps you connect to your trailer’s wiring correctly without confusion.
• Secure plug engagement: When the trailer’s male 7-pin plug is inserted into this socket, the design of the contacts and the spring tension ensure a tight fit. This prevents the connection from coming loose or wobbling even over bumpy roads. For additional security, many setups allow use of a clip or pin to lock the plug in place (if your system supports it), though generally the friction fit is enough.
• Universal compatibility: This socket is compatible with all passenger vehicles, SUVs, and pickups equipped with a standard 7-pin trailer wiring interface. It’s perfect for trailers, caravans, boat trailers, bike carrier light boards, and more. The metal build is especially favored for boat trailers or commercial use where durability in wet conditions is crucial.

By installing this 7-pin female trailer socket, you ensure a safe and stable electrical link for your trailer’s lights and accessories. Installation is typically done with two bolts onto a bracket or plate on the tow bar (mounting hardware may be included in some kits or purchased separately). Manufactured in the European Union, this product guarantees high quality and compliance with current safety standards. It’s a small but vital piece of towing equipment that helps you tow legally and confidently, knowing your trailer’s lights will perform correctly.
