90 hp LTR 2 stroke

Anyone know what wires from the controls go to the tachometer??? Looks like the tach has 3 terminals for hookups.

Thanks

Not sure what tach or year model motor, but this should be correct

Black= ground(negative)
yellow= key on power (12+)
Green= tach signal

And possibly blue= lights
