Starting mid of February 2018, there will be only one 50cm NYLON filament included.
⬢There are two NYLON filaments included in the kit with lengths 50 and 30 cm. Both have Ø 3 mm. For this step please use the longer one and DON'T CUT any of them!
Push it all the way down. If you experience difficulties when inserting the filament use pliers to make a sharp tip on the filament.
The filament is for the support of the whole harness. Don't cut it, it'll go all the way with the wires to the cover for electronics.
Note the correct orientation of nylon filament, it needs to point up as shown in the picture!
Nylon filament is pictured in orange colour, but in your kit can be the black version, which is the same, just different colour.
