I need to know what harness do you plug in the knock sensor. I can't find it these are the only ones that are not plugged in????

 

From my experience I test continuity from the plug to where the ecu plugs in(search for a ecu pinout for your car) and trace the harness till you find the correct plug.

 

Greens your alternator. Knock is usually a single blue wire.

 

That green is not the alternator, most likely the power steering pressure switch.

 

well on my carthegreen is the iacv sensor just throwing ideas i have a b16

 

Either of them can be for the knock sensor. But looks like the green plug has one wire in it so it could be for the knock sensor,some one change the plug. The gray could be for power steering pressure sensor or Evap purge solenoid but could be for something else. It's hard to say for sure without knowing what the wire colors are in the plug and even knowing the colors it's still tricky to say as some one could have swapped the plugs.
