How to install tach?

I'm not a fan of the imfamous 5" tach.

I'm curious is the install same as it would be to install a A/F gauge or oil temp gauge?

air fuel gets hooked into you o2 sensor wire coming out of the ECU. and the oil temp, you need a sending unit that is place right above your drain plug. you need to drill your oil pan. so its a little different
