What is this in my 5.0 engine? (pic)

[HighMileageVert]

So I was finally getting around to changing the leaky hoses to my egr spacer, when I noticed this thing just hanging down under my mass air sensor.....what is it? My guess is the knock sensor.

its your wide open ac relay switch or if you have a 92-93 its a fuelpump relay or your woac relay switch

 

[HighMileageVert]

Ah, I should have mentioned; it's a 90 lx vert with AC (though not working).

If it's the wo ac relay, should it be mounted somewhere?

 

[gaslight]

If you look around some more you will find more things just hanging there.

Should be mounted to the fender below the MAF meter. There might be a clip down there that it was attached too

Do Mustangs even have knock sensors?

 

[thompsonsd]

Yep, their in the lower intake manifold, big whiteish things...

No 5.0's do NOT have knock sensors, atleast never that I have seen . That "big whiteish thing" as you put it is the ACT in the lower manifold.

No flames just FYI

4.6L and 2.3L Mustangs do.


5.0's are knockerless

Yup no knock sensors, and yup ACT stands for Air Charge Temp sensor.
