Information







NOTE:
- The repair instructions document "Main wire harness" is divided into several chapters because of its size.
- For body repairs, refer to the specific chapters on installing and removing individual sections of wiring.

ATTENTION:
- The main wire harness contains all airbag lines, antenna lines and optical waveguides.
- The main wire harness must therefore not be cut for major repair work and must be replaced complete.
- If individual lines are damaged, isolate them (disconnect, remove plug contacts from plug connections etc.) and replace the original wire harness by installing new lines.
