Aftermarket Coolant Temperature Sensor - Where To Install?

I would agree that the back of the water pump housing is the best spot for an ELECTRIC gauge. On the S5 housing, depending on the cars options, there is already a flat spot milled that is the perfect size for a 3/8"NPT sender to fit. My only fuss is that I prefer a full-sweep gauge and in a larger size like 2-5/8". There are very few gauges that meet both of those demands and still ring in under $150, which is why I went with mechanical. My Autometer Sport Comp reads uber fast and was only around $60. It's pretty interesting seeing the thermostat open up and see the gauge go from dead to 185 in about 1 second.
