Take out two short PTFE tubes from the tool box |
Insert the two PTFE tubes into the two quick-connect couplings |
Take off the filament loading tubes set:

The steel wire and the filament loading tubes are taped to the surface of the build plate glass

Tight the two short screws to mount the end of the wire to the drag chain bracket behind the Z motor.

Install the other end of the steel wire to the underneath of the filament sensor panel.

This is what the tubes look like after loading the filaments, the tubes are not connected.

Please don't connect the short tubes above the extruders with the long filament loading tubes.
Why don't connect the tubes?
When the extruder withdraws or retracts the filament, it cannot push the filament back to the filament spool for nearly two meters.
The unconnected areas of the tubes are to store the filaments pulled out by the extruders.

This is what it looks like during printing
