RPM gauge

[adamforsythe]

Hello,
I will be getting new gauges for my 1985 K5 Blazer. Well where the gas gauge is I will be installing a RPM gauge and I will move the gas gauge over where there is a extra spot for a gauge. Now what do I need to do to install a RPM gauge?
Thanks
Adam

Your "RPM" guage is more commonly referred to as a tachometer.
