Velvac 055040 7-Way Socket
This Velvac 055040 socket provides a 7-way connection for trailer, plow and towing equipment. It is built for users who need a standard trailer wiring interface without integrated circuit breakers. The zinc-plated brass contacts resist corrosion in outdoor conditions. The plastic insulation protects the internal terminals from moisture and debris.
Installation and common issues
The socket accepts No. 8 ring terminals for secure wire attachment. Installation requires crimping or soldering the terminals to the vehicle or trailer harness. A common issue is loose terminal connections causing intermittent lighting or brake signals. Corrosion can develop at the contact points if the housing seal is damaged or missing.
7-way connection type
The defining specification is the 7-way connection type configured without circuit breakers. This matches standard RV and utility trailer wiring pinouts for lighting and auxiliary power. Buyers needing built-in overload protection must select a different socket style. This unit supplies the raw connection points only.
