Interesting that the radiator/fan combo didn't include a bung. If it's a 
Wizard radiator I'd question them as my Wizard/Spal combo pack 
(http://tr6.danielsonfamily.org/Radiator.htm) came the bung in the upper 
right corner.

Ideally you want the sensor in the radiator but I guess you could mount it 
in the hose coming out of the thermostat like I did for the coolant sensor 
in my TBI installation. There's a picture here

You should also consider a 3-way fan switch: auto-on, off, manual-on.
