Doesn't matter, problem solved.

refit the temp sensor that matching your wiring, it will run shitty as that controls the auto choke which will make it add more fuel or take away as the engine gets hot, once that is done re check, depenmding on what type of sensor it is, you will need a multimeter set to ohms for measuring resistance. with the sensor unplugged use the multi meter on the connections and as the car gets warm the resistance should change as the temp gets warm. it should drop if im think of the right sensor. if the sensors working if it does check the wiring from the sensor for breaks or corrosion

Nevermind, swapped the thermostat housing over with all the original sensors, now it's perfect, goes up to running temperature, stays there, and the fan works too.
