SRS deployment harness connectors are Orange, except for passenger-side air bag module connector which is Violet. The SRS connectors between air bag module(s) and crash sensor have gold-plated terminals for maximum conductivity. These colored connectors contain a safety shorting spring in the male half of connector. When connectors are disconnected, safety shorting spring spreads open to touch both terminals, preventing accidental deployment of air bag by static electricity or careless handling.
