2002 Yukon Xl - Knoick Sensor Location?

[RAinColorado]

Engine light came on today for me. Code reader tells me PO332. So it's the rear Knock Sensor - -I found the replacement part. I can't find where it's located.

 

Conflicting info from repair store - - Diagram looks like the sensor is accessible from below the block. Some info online shows sensors under the intake manifold.

 

Help - - Where are the sensors to be replaced?

Thx.
