Winston Products 1430 7-blade Trailer Wiring Connector

Product Description

The WINSTON PRODUCTS 1430 is a 7-blade trailer light wiring connector designed to establish electrical connections between a tow vehicle and a trailer. The single-housing design plugs directly into the vehicle's electrical socket and splices into the trailer wiring harness, providing a secure and reliable connection. Built from corrosion-resistant plastic, it is engineered to hold up in extreme weather conditions. Licensed electricians and experienced DIYers familiar with trailer wiring regularly install this type of connector in towing setups where a robust, multi-function electrical link is required.

This connector is commonly specified for large trailers and RV applications where multiple lighting and braking circuits must be routed through a single interface. The 7-blade configuration supports taillights, brake lights, turn signals, electric brake control, auxiliary 12-volt power, ground, and reverse lights — making it a complete wiring solution for fully equipped trailer rigs. Its ergonomic housing simplifies plug-in and removal in the field.
