Where is the engine coolant temperature sensor located at on the engine of a 1987 Pontiac trans am gta 350 cc engine?

there are 2. the one that goes to the dashboard coolant temp sensor is on the left bank under the exhaust manifold in the water jacket on the block.it looks like a lil pin head with a hook on it. the one that goes to the pcm is on the intake manifold next to the water neck.
