Installing wire harness for airbag

WARNING:
Incorrect handling of airbag units.
- Danger of injury and material damage.

- Always observe the safety regulations for handling airbag units.
- Remove ignition key. Disconnect battery. Route or isolate ground strap so that all contact with a ground carrier (e.g. body, seat frame) is avoided.
- Before the connector is disconnected from the triggering unit, always wait for 1 minute before disconnecting the battery. The airbag triggering unit must not be removed with the plug plugged in.












1. Disconnect the connectors of the damaged airbag line on the affected components. The illustration shows the connector on the acceleration sensor under the seat as an example.
2. Insert the latch -2- on the connector -1- (-arrow A-) until it engages securely.
3. Release locking mechanism on the latch -2- (-arrow B-) and pull off connector -1- (-arrow C-).
4. Cut off the connector of the damaged airbag line, isolate it and tie it to the wire harness.
