2.3 Installation Steps (General)

1. Carefully remove the original car display and trim panels.
2. Connect the provided wire harnesses to the original car's wiring. Ensure all connections are secure.
3. Connect the fiber optic cable:
   • The original car power cord is connected to the conversion cable.

   • Connect the fiber optic cable to the host unit.

Note on Switch Panel Relocation: The original switch panel (e.g., for passenger airbag, ride height, parking sensors) located between the original screen and gauge cluster will need to be removed and relocated. An extension cable is provided for this purpose, often routed to the glove box.
