Modular Wire Routing With Ridged Tube on Front Seat

Modular Wire Routing with Ridged Tube on Front Seat

Special tools, testers and auxiliary items required

• Trim removal wedge (3409)






General Information

With the introduction of modular wiring routing (Modular Light or Modular), the complete sheathing of the entire wiring harness with a fabric strap between the seat tray and the connectors to the connector station has been eliminated. A two-shell corrugated pipe in which the individual wires are routed separately has been implemented for this purpose.
