On the side of the motor you will have a terminal strip where all the wires connect. Locate the gray wire that is the signal wire for the tach. Now if you have a Johnson side mount control with key switch there is a plug under the key that has all the wires for the tach hook up. Gray, purple and black. Post back with questions.This is just general info till I get more info from you like a model number.
