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?

Re: 1990 Yamaha tach install

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
