The compound gauge is an instrument to measure pressures, positive or negative.
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
It goes to the temp gauge which is usually screwed in the head between the manifold on the drivers side, or into the thermost housing on the intake manifold.
The Compound Gauge measures above and below atmospheric pressure (in psig and inches of mercury).

using master vacuum gauge and master pressure gauge
A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.
pressure and temperature
i need to explain what an absolute pressure gauge measures
