What This Adapter Does

The Hopkins Towing 47340 wiring adapter connects a vehicle with a 7-way blade socket to a trailer that uses a 4-way flat plug. It is built for towing and plow equipment where a simple plug-in link is required. The adapter meets SAE J1239 and J2863 standards and includes a dust cover to protect the contacts when not in use.

Check Your Vehicle and Trailer Sockets

Before ordering, confirm that the tow vehicle has a 7-way blade connector and the trailer uses a 4-way flat connector. The adapter is designed for a direct plug-in fit with those two specific interfaces. Verify that the existing wiring on both sides is in good condition so the adapter can verify electrical continuity without faults.

How It Fits in the Tow Setup

The black plastic housing is impact and corrosion resistant and features a pull-grip design for easy connection and removal. It bridges the vehicle and trailer wiring without additional tools, freeing you from splicing or rewiring the existing harness. The included dust cover keeps the 7-way blade end clean during storage.
