You can just zip tie to the shroud however look for a small hole on the side of the shroud I have a feeling that it breathes though a hole that is blown through from the fan to ensure ita getting fresh not stale air

That's the really strange thing I find with these sensors. They are supposed to be sniffing for hydrocarbons in the air so they can close the outside air intake. Except, they aren't exposed to fresh air, at least that I can tell. Where they mount to the cowl has no opening into the fresh air flow of the cowl. I'm not sure how these sensors are supposed to smell fresh incoming air as I don't see any way in which they are exposed to it.
