There is no dedicated place to pick up oil pressure. Some have been known to remove the Yamaha oil pressure sensor and T in a fitting so that oil pressure is provided to both the Yamaha sensor and a non-OEM gauge.

For water temperature you can add the optional temperature sender. It goes into a fitting at the top of a cylinder head. Whether the Yamaha sender will be compatible with a Faria gauge is unknown to me.

Water pressure is obtained from a port on top of a cylinder head as well. One port in one cylinder head is for the temperature sender and the other port in the other cylinder head is for a water pressure fitting.
