I would like to add a coolant temp gauge and oil pressure gauge to my '79 Regal with a 301. I am not a huge fan of "idiot lights"; I like to see "real time" info on these things. I searched around and didn't see this covered; if I missed a previous thread, I apologize. Has anyone done this before? Is it possible to preserve the idiot lights as well when adding these gauges, or do I have to forgo the lights and use the existing engine connection points for the gauges? Any help would be appreciated. Thanks.
