Does anyone know of a guide for installing gauges like oil pressure, coolant pressure (or temperature, whichever isn't covered by the lights), and battery voltage?

I've been wanting to add some gauges, but I have no clue what it would take to install those gauges.

Also, does anyone have pictures of where their gauge pods are? Obviously, an A-pillar pod won't work, and I'd rather not give up my dash compartment.
