It comes in a TO-92 package (small plastic transistor w/ 3 skinny leads). We can power it off the 12V that we run the water height sensor off (which will also be the 12V for the Falmouth Pressure). The temp sensor will need one return lead for it's output current. (That should make a total of five for this housing, four for the height sensor and one for the temp sensor. If there is room in the housing I'd like to include a transient suppressor zener and possibly a bypass capacitor, both small devices also. Let me know and I'll dig up drawings for all three items. -Ed
