I use 14 gauge wire from the sensors through out. I had a rotary switch on the Z3.
Since I just wanted two, I want with the toggle switch. Easier to wire for the wire size.
I use the 250 degree water temperature gauge with two 250 degree sensors.

One in the block drain and the other in the sump plate that Daniel and Randy came up with.

The gauge between 180 and 220 are 10 degree increments. Easier to read the oil temperature.
The stock oil temperature cluster gauge is buffered just like the water gauge in your car.
