Coolant temp sensor? •__•

[NHTKID]

Man, I've searched and have not been able to find a definite answer to my question. I have the 97 s13 sr with the j4 ecu, what year coolant temp sensors are compatible? It says 91-94 ser's here on zilvia but I tried a 93, it didnt work, maybe it was a bad one?

I apologize ahead of time if this question is ignorant. Just trying to get my car running. Thanks guys

I only ask because my wiring specialties harness has a round plug, not the square one.. The factory sensor that came out was bad and also a round one, not the square one. But all the ones online ect that are said to be needed are the square ones
