Name that Part

[twowire]

Sorry to bother with something like this.
Took the plenum off recently and have not put it back together yet.
Noticed this part (in picture) laying on the ecm.
Now, I probably put it there, but I don't remember specifically.
Isn't memory failure is grand! Seems like a vacuum connector I guess?
Hopefully I can find it as it goes back together when it happens.
I'll probably do a V8 if I find out where it goes lol. figured I'd throw it out to the experts.


Know where it goes?
I thought it might have been the map hose, but that hose has both connectors on it so that's not it.
