I have for sale a BNIB HRC wiring loom and derestrictor which came with an MC21, so I am guesssing it is for that. Part numbers are as follows;
30490-NKD-840 - Outside bag
30491-NKD-840 - Derestrictor bag
32100-NKD-840 - Wiring loom bag
What's it worth? Offering it here for sale, otherwise will go on Fleabay... Will ship worldwide, freight cost should be small due to being reasonably light.
