Thank you for your reply. I could definitely use your help as my dealer seems to not have any clue about this.
Please check the link below and please let me know if you have the same charger:
If you do, mine come with 4 items in the package.
1. the charger. (Pic 2)
2. the US electrical outlet converter plug.
3. the cable that connects to the charger. (Pic 2)
4. another cable that has male connector (looks like DDA port) but has a pigtail connectors. (for the battery). (Pic 3)
I have included a pic of my DDA port, which are located underneath the seat. (pic 4).
Please advice and in the mean time, I may call other dealer to see if they have more info.
