Mystery plug

[Alkovary]

Hello everyone, I just finished up changing a head and all the gaskets. I was pretty confident I had all the connections back where they belonged but today I noticed a grey wire running up from the font of the engine bay on the passengers side. It looks like it might be some sort of vaccum tube but I'm not entirely sure. My question is what does this plug into and where?

Ok, first and foremost "wire" and "vacuum tube" are two very very different things.

Second, it's a vacuum line. It goes on a nipple on the heater bypass valve.

That was what it went too. I just wasn't sure because I've never messed around with vaccum lines before so I was t sure if they were all gonna have that heat shielding stuff around them. Thank you all for the help though.
