Location of Temp Sensor Switch

Hi all, I am struggling to find the location of the coolant temperature switch. Could anyone snap a pic or give me some direction as to where it is? (12a 1.1L) Thank you.

#1 water temperatureswitch is in the back of the thermostat housing. It controls your choke magnet and the hot start assist system. #2 water temperatureswitch is in the bottom of the radiator on the left side. It sends a voltage signal to the ECU. Top of the radiator is the coolant level sensor. Under the oil filter is the temperature gauge sending unit. Large sender on the left side of oil pan is oil level sender. Small sender in the same place is sub zero start sender.
