I want to order a set of autometer gauges for my car. I want the electric full sweep ones. The car is a 93 soon to be with a 408. I figured I would order fuel pressure, oil pressure and water temp. I am going to order the gauge pod that replaces the center heater vent, so the gauges must be 2 5/8 Any suggestions on which autometer gauges to order? Also I know the basics as to how to wire them, to the keyed on source and the lights, however can I wire them all to the same wire for a keyed on source? And I know that most of the sending units come with the gauges, are they are universal so they will work on my car? Thanks for the help.
