ahhhhhhh i see your confustion
the sensor you bought is for AC thermal switch only, see that word switch?
Do not confuse the AC temperature switch with ECT the former is just switch
the ect only fits the the rear of the head and has 3 pins, and is on the exit rear head housing.. that hottest place for coolant. exiting head.
lets use advance auto parts
this is the correct sensor

the AC switch is not a sensor, no sensor is a switch .
2pins and is not a sensor

see?
if the engine truly overheats,no proof yet, the IR Gun said NO.
consider this fact: the ect defective will never make the engine every overheat.
the 2nd set of pins in the ECT is crude, dash guage sensor, and that can not cause overheating ever, sure it lies to the driver, only
symptoms of overheating are
sure dash gauge reads too high but your sensor was never replaced.
the engine pings
the loss of power
the rad side tank blowA steam or huge blows of hot water so violent the side tank (overflow) WILL BLOW OFF THE TANK
CEL LAMP GOWS AND SCANS SHOW THE DTC FOR OVERHEATING;
THE SCAN TOOL READS THE ECT ACCURATE SIDE OF THE 2 SENSORS IN SIDE OF THE ECT.
the first thing to check are
fan belt missing or slipping
then check water levels and 50% consentration of antifreeze never ever run pure water.
next a new thermostat, . and full flush on such and old car.
if it only over heats parked, (pump ,rad or fan dead or weak) but is ok moving fast, blame fan.
