BLOW 4624# is a 13-pin plastic trailer socket designed to provide a reliable electrical connection between a towing vehicle and trailers or caravans. The connector offers a full 13‑pole interface for lighting circuits, indicators, reverse lamp, fog lamp and additional auxiliary circuits. Constructed from durable plastic to resist corrosion and road contamination, this vehicle connector is intended for standard trailer wiring harnesses and typical on-road towing applications.
Advantages
The plastic housing ensures resistance to rust and reduces maintenance compared with metal sockets. Thirteen contact positions support complete trailer lighting and auxiliary functions in a single connector, simplifying installation and reducing the need for separate adapters. The design is compatible with common trailer wiring standards and provides compact, lightweight performance suitable for passenger cars, vans and light commercial vehicles.

- Connecting trailer or caravan lighting and signaling circuits
- Reversing and fog lamp feed for towed units
- Auxiliary power supply for trailer accessories
- Standard towing on-road applications with 13‑pin wiring harnesses
Key specifications
- Contact count: 13 pins for lighting, indicators and auxiliary circuits
- Material: corrosion-resistant plastic housing
- Compatibility: conforms to standard 13‑pole trailer wiring layouts
- Mounting type: panel or cable-mountable vehicle connector format
- Weight and dimensions: compact, lightweight design suitable for vehicle mounting
How to use
Install the trailer socket in the vehicle’s tow-bar mounting location or panel cutout and wire each conductor to the corresponding vehicle circuit according to the 13‑pin layout. Ensure wire terminations are secure and insulated, and that contact surfaces are clean before mating with the trailer plug. After installation, test all lighting functions, indicators, reverse and fog lamps, and any auxiliary circuits with the trailer connected to confirm proper operation.
Usage recommendations
Regularly inspect the socket for dirt, moisture and worn contacts; clean with a suitable electrical contact cleaner and protect with dielectric grease if exposed to frequent wet conditions. Use a wiring diagram matching the vehicle and trailer standards during installation, and replace the connector if contacts are corroded or mechanical damage is evident.
