I would not put both the temp gage sender and the alarm switch in a tee. I would be concerned that the water in the tee would not circulate and you would not get an accurate reading. The switch can be installed anywhere in the water circuit. If you install it in a hose, remember that it requires a ground to complete the circuit.

Re: Installing a temp SWITCH
Dave, you may be able to find a replacement sender that has a second separate alarm circuit (contacts) built into it. A good parts counter can look up whatever sender you have and see if there's something available in the same size.

Installing a temp SWITCH
My Universal 5424 has a standard "temp sending sensor" installed and I was considering adding a "temp SWITCH" connected to my muliti-purpose audio warning buzzer. I added the aural warning to the oil light circuit because it's a little late when the engine seizes because you didn't see the oil light (which is on the engine panel hidden from plain sight), so I thought the same thing for engine temp.
The temp sending unit goes right into the thermostat housing area. If I were to add an elbow there to add a switch, do you think the 2 would get water temp data acurately enough?
