Britax B4 7 Pin Flat Plastic Trailer Plug

Trailer Vision 7 Pin Flat trailer side plug with rubber cover

The Trailer Vision 7 Pin Flat Trailer Side Plug is a durable and reliable solution for connecting trailer wiring, designed to withstand Australian conditions. Featuring a protective rubber cover, this plug helps keep dirt and moisture out of the contacts when not in use, improving longevity and electrical reliability.

Built to ADR 42/03 standards, this 7 pin flat plastic plug uses nickel-plated brass pins with Phillips head screws to ensure strong conductivity and secure wiring. The included plastic wire cap provides added strain relief and protection during installation.

Trailer Vision's unique spring-loaded design compresses when mated with the vehicle-side socket, creating greater contact pressure. This reduces vibration-related issues and minimises the risk of loose or intermittent connections while towing.

Installation is straightforward, with colour-coded instructions supplied to match wire colours to pin numbers, making it suitable for both DIY and professional fitment.
