its the greenish blue wire on the obd2 diagnostic port right near the hood latch its the farthest left wire the last left column thats the tach wire never use a test light on these obd 2 cars always use a computer safe test light and yes there is a difference between the two test lights. you cant blow up a tach if anybody told you that there stupid you can fry a tach but only if you reverse polarity it by putting power to ground and ground to power but not by trying to hook up a tach wire. if it didnt come with a tach you still have a tach wire. the wiring is the same through every yaris even if they didnt come with a tach its still wired because the ecu still needs a tach signal to know when to fire the coils since there is no distributor
