As Jim mention, probably a good idea to have a spare. I had a persistent issue with my modules several years ago. Substandard wire in them (in my opinion). Several areas of the wires broken inside of the insulation. I had to cut/spice/repair several sections of my modules and wires from the stator.
Granted I come from experience in building military grade electronical test equipment for fighter aircraft, so was used to using very high quality wires. The wire that Rotax (ducati) uses is pure junk!
