You didn't give any info regarding year, trim level, engine, hatch/combi...

The ground wire is a screen and connects directly to the ignitor (usually by one of the mounting screws). There are numerous wiring variants, but the earth usually originates on the 'C' pillar (or luggage compartment for the combi).

octavia II sedan from 2006. yes, one end of the wire go to ground point in rear compartment, on pillar c: one on the right and one for the left.

but the end for airbag don't know were is connected. i attach apicture with the connector for airbag. It is visible the 2 wires 1 and 2 but is none for groud

The ground wire is a screen - it does not go to the connector.

The ground wire usually has a ring on the end and is secured to the airbag unit with a screw.

ok, thank you very much
