General LSX Automobile Discussion - coolant temp sensor for a 98 ls1 part#?

I need to know the correct part # for mine,
Supposedly the 98 camaros had a '3 pin' coolant temp sensor.. but on the oreilys website it shows a '2 pin' .. and obviously i need the correct one, dont want to order the wrong one and play guess and check.. mines going out and surging bad so i need an answer quick if at all possible

Thanks

nvm i found it
