Winston Products 1441 4-wire Flat Trailer Connector

Product Description

The WINSTON PRODUCTS 1441 is a 4-wire flat trailer wiring connector designed to establish electrical connections between a tow vehicle and a trailer. The one-piece construction features bonded wiring that carries stop, turn, ground, and taillight signals across a single, compact assembly. Built from corrosion-resistant plastic, this connector is engineered to hold up against moisture, road debris, and temperature extremes encountered in regular towing service. It is a practical, field-ready solution for electricians, auto technicians, and experienced DIYers working on light-duty trailer wiring setups.

This connector is suited for residential and light commercial towing applications where a standard 4-flat wiring configuration is required. It is commonly installed on utility trailers, boat trailers, and small cargo trailers that require basic lighting circuit connectivity. The compact form factor and one-piece design make it well suited for quick roadside repairs or routine trailer wiring maintenance. The ergonomic plastic housing allows for fast, tool-minimal installation in the field.

Installation Notes

Installation is typically performed by an auto technician or experienced trailer wiring technician. Disconnect the tow vehicle from any power source before making or breaking wiring connections. Verify that wire gauge and circuit load are appropriate for the trailer lighting system being connected. Follow applicable vehicle and trailer wiring standards when routing and securing the harness to prevent chafing or connector strain.
