Product information

Description

The Trailer plug BLOW 4857# aluminium 7-pin trailer connector is a compact, metal-bodied electrical connector designed to provide a reliable interface between a towing vehicle and a trailer. Constructed with an aluminium housing for improved corrosion resistance, this 7-pin plug supports standard lighting and signal circuits used on trailers, caravans and utility trailers. Its compact form factor and durable materials make it suitable for installations where a robust, weather-resistant connection is required.

Advantages

The aluminium housing offers enhanced corrosion resistance compared with many plastic alternatives, extending service life in outdoor and marine environments. A seven-contact configuration supplies all common trailer lighting and signal circuits in a single plug, simplifying wiring and connection. The metal body provides mechanical durability against impacts and wear, while the compact design allows for installation in confined mounting locations. The connector is compatible with standard 7-pin trailer socket wiring conventions, facilitating straightforward replacement or retrofit.

Suitable for

  • Connecting vehicle lighting and signal circuits to trailers and caravans
  • Utility trailers, boat trailers and small commercial trailers
  • Retrofit or replacement of worn 7-pin trailer plugs in towing setups

Key specifications

  • Number of contacts: 7
  • Housing material: aluminium for corrosion resistance
  • Design: compact, metal-bodied 7-pin plug suitable for external mounting
  • Function: supplies lighting, turn signal and auxiliary circuits for trailers
  • Compatibility: fits standard 7-pin trailer sockets and wiring conventions

How to use

Prepare vehicle and trailer wiring by ensuring power is disconnected before installation. Strip and terminate each conductor according to the connector’s contact positions and the vehicle/trailer wiring scheme, following standard 7-pin color codes. Secure the cable and fasten the plug housing to prevent moisture ingress and mechanical strain on the conductors. After assembly, connect the plug to the trailer socket and test each lighting and signal circuit to confirm correct operation before towing.

Usage recommendations

Inspect contacts and housing periodically for corrosion, deformation or wear. Use dielectric grease on contact surfaces to improve corrosion protection and maintain reliable electrical contact. Ensure mounting hardware and cable clamps are tightened to avoid vibration-related loosening during use.
