Tach connection

[DavidD]

I have a 97 evinrude 90 that the previous owner had installed on a 87 ebbtide dynatrak bass boat. The mechanic did not connect the tach. Does anyone know what connection on the motor the tach connects to?

Gray wire in the "engine" harness or the three pin connector right below the key on the control box.

David, You will likely also need +12VDC (purple wire) and ground (Black wire).
