SRS wiring harness outside housing is Yellow. All SRS connectors between air bag module and SRS control unit have gold-plated terminals for maximum conductivity. When SRS 2-pin connectors are disconnected, a safety shorting spring inside each connector spreads open to touch both terminals. Safety shorting spring prevents accidental operation of air bag system by static electricity or careless handling. Safety shorting spring contact is automatically disconnected when SRS connectors are reconnected.
