It's working for me.. quick reply.

If you had a electronic water temp gauge, you could tap the wires from the sending unit... you don't, I assume.

Since that is a problem for you, the next best place to put it is either in the thermostat housing, (not a good place) or the side of the radiator... I've had pipe nipples brazed into the side of the lower tank before, so that it could be threaded in securely, and didn't need to be sealed.
