    5. B0069RIC01
      B006DHE Install in this Direction
      B006GBM Side A

      Slide it until it contacts side A.

    6. B006DCAC01
      B006DHE Install in this Direction

      Contact side A.

      Note

      Do not contact side A with the main body ECU (multiplex network body ECU) too hard.

    7. B006AR1C01
      *a Center of Rotation(Contacts Surface A)
      B006DHE Rotate in this Direction
      B006A7GC01
      *a Center of Rotation(Contacts Surface A)
      B006DHE Rotate in this Direction

      While pressing the main body ECU (multiplex network body ECU) against side A (center of rotation) of the instrument panel junction block assembly, rotate it until it enters the lock of the instrument panel junction block assembly.

      Tech Tips

      The center of rotation is the one that contacts surface A.
