Ditto.
I have a 90 with an SR and the shit wouldn't work... no luck with the dohc tach either.
I just ended up buying an autometer
tach adapter. Hook it up to a positive coil wire, and walla. Shit is kinda expensive, but if you ever want a working tach, you have to buy something such as that adapter.
