temperature sensor 91 amigo

the temperature gauge in my dash doesnt move as the engine warms up (91 2.6L amigo)
where is the temperature sending unit on the engine so i can check to see if i knocked a wire loose or if it just needs to be replaced?

it is right side on intake near battery- there are 3 different sensors on this yr&2.6 but this is the one for the guage is is a small spade type connector & hard for the parts guys to find i have changed mine 2 times because the terminal breaks off sensor easy
