What do you mean you don't "Believe" so? It either is or it isn't.
And you might also want to mention that the car is boosted.

Just gonna go by visual ID:

1st pic: 4 wire connector is oxygen sensor, could be either primary or secondary, post wire colors, 2 wire connector is reverse switch (post colors)

2nd pic: evap control canister vent shut valve (post wire colors)

3rd pic: either connector could be intake air temp sensor (post colors) and evap purge solenoid (post colors)

^^^That's the method. Post the wire colors for each. I'll remember that for future since a couple of connectors can mistakenly be switched (to bad effect).
