Zongshen makes a lot of parts for a lot of different manufacturers including United Motors (my bike) so maybe they're similar and can me modded. With mine I found few of honda and suzuki parts or generic chinese parts on ebay that with a little bit of modding worked well. Can you post a pic of the harness to see if it looks like something similar? Also you can check here
