What exactly did you do with the electronics to make the headlight, Tachometre and the indicators work? I'm a little new to this :) Your bike looks awesome!
We buy proper ones, Kellerman, Motogadget and others. Motogadget speedo cost a lot, as option you can buy good one from Custom Chrome or Parts Europe. They selling speedos with E certification and warranty. How to connect: proper papers attached in box and you will connect everything. Even online files with all info you get from internet. Motogadget providing online descriptions. Don't buy cheep Chinese parts, its not work properly- especially speedos. Good luck with your project :)
