Can not find knock sensor. I have a repair manual and it says it is under manifold and Autozone said that is where it was. But it not there.

See picture. It is under upper intake manifold do not torque over 15 ft lbs or you will mess up the new sensor.

Hello again guys. I have added a video.I've looked all over don't believe there was one on the 99. But book and autozone says there one. I'm baffled. Even ran scan decoder which says knock sensor low input. Even found knock sensor wiring connector which had electrical tape on it. In pic I found where sensor goes but it not threaded. Not sure what to do

This isn't a very good pic of what you want as it doesn't show the whole intake check on upper intake on bottom and where does this electrical connection lead see pic arrow
