SRS harness connectors are Green, except for passenger-side air bag module connector, which is Red. The connectors between air bag module(s)/seat belt tensioners and sensor module has a built-in capacitor connected in series with one of the cables. The capacitor prevents accidental deployment of air bag by static electricity or careless handling. Resistance cannot be measured between contacts as the capacitor blocks measurement. A "service hole is provided in the connector to facilitate fault-tracing. See Fig 1.
