1998 mariner 150 efi. Where does the tachometer wire connect to the motor? Tach, speedometer and warning piezo have stopped working and I read somewhere that the warning alarm and light are tied to the tach.
Can't figure out where tachometer wire goes on motor or the color of the tach wire to the motor. This boat has been great but now having some issues. Tach and speedo quit at the same time and the light and audible alarm both quit too. Can't find any blown fuses. Help would be appreciated.
