The Deutsch Autosport AS connector series is the most ubiquitous connector in motor racing. Developed from Euro-Fighter specifications, these connectors have been trimmed down for maximum weight savings while still providing a solid, weather-resistant connection.  The AS is available in a variety of sizes and configurations, so it will fit just about any need.  All AS connectors are sold as sets; each set includes the connector, pins, and insertion/extraction tool.
