Connection from the battery

@roshan51846 you are not giving us a lot of information here. I would expect more than just a few words if you are seriously trying to fix your motorcycle. Anyhow, there should be a wiring harness connecting this all together. IF there are individual things that are disconnected or not working, use the schematics to trace the errors.

While you work on your motorcycle, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
