quick question, my 1.3 meter panel does not have a rpm gauge. if i get the three gauges from a 1.5 (tacho, speedo, and fuel&temp), can i place them on my existing 1.3 meter panel? since my car doesnt have a rpm meter originally, how to i hook up the new rpm gauge to get a reading?

i hope you understand my question, i'm not trying to swap 1.3 meter panel with a 1.5 panel, just want to replace the gauges in my current panel with gauges from a 1.5.. thanks
