I'm so lost on what to do here, if anyone has any videos, or how tos, could you point me that way?

 

Just pull the intake manifold off, and the sensors are right there on the valley pan.

Just be careful not to break the oil pressure sender behind the intake.

your not necessarily swapping your intake but it does show all the required bolts to be removed. a suggestion for the back 4 bolts on the intake manifold is to hold them all up with a rubber band at their highest point or to put tape on them once you have them raised up

 

Knocker sensor. We all have one.
