Re: Tachometer Hookup Help - New Cluster!
You're welcome!
I don't think there is much risk of frying the tach by not using the filter. The filter basically just blocks higher frequency "noise" from the signal that could potentially cause erratic / jumpy tach readings and / or interfere with radio reception. But since you already have the filter, you might as well go ahead and use it to ensure a nice clean signal to the tach.
