  • 1990 Yamaha tach install

    Hey guys, I was wondering how hard it would be to install a tach on my 1990 yamaha 50ESD-JD. Just wanted to get an idea before i went out and bought one to install on it.

    Thanks!

    Does the tach plug into some of the extra plugs that I have on my control box?

      yes there should be aset of wires at control:
      Green is tach signal
      Yellow if key on 12 V power
      Black is ground

      There is a red that is 12V power hot all the time but you should not need that to the tach
