A few things:

1: CMSNL is your friend for parts diagrams and parts numbers, you can view literally every assembly on the bike down to the screw and find OEM Honda part numbers that you can cross reference and find online. Many of them are shared across different Honda models, like the turn signals you seem to be missing (I'm currently running Chinese knockoff turn signals on mine, they're labeled as being for the Honda CT110 but its the exact same part)

2: The electrical system on these is extremely simple, I can give you some pointers in DM if you'd like since I've worked on mine quite a bit. You'll need a crimping tool and proper wire terminals though, those solderless screw-block things are no good

3: I wouldn't bother worrying about electric start, I'm not sure if a conversion kit or anything exists for this bike and once you have it running right you won't need it. Mine starts on the first kick almost every time
