4. Check locking mechanisms, connector housing and contacts for possible damage and replace damaged parts if necessary.

Information 

• New electric lines are secured at the mounting points for the old electric lines. 
• The damaged electric wire harness remains installed in the vehicle. 
• The damaged electric wire harness is only disconnected directly at connected components. 

Information 

• Do not damage the insulation on the optical waveguides during installation. 

Information 

The range of spare parts available for optical waveguides depends on equipment. There is a specific set containing the individual optical waveguides to suit the equipment in the vehicle.

Select the required optical waveguide and remove it from the set.
