What is this?

Hey guys.... still working on my dash when I came across this and can not find anything about it. I'm stumped. It's next to the ash tray in the roadrunner dash. What is it?
Any help will be greatly appreciated. Thanks

Looks like an electrically operated vacuum port.
Don't know what for exactly.

part of an AIR GRABBER set up

You should have or will need the rest of this to help your Air Grabber function

Thanks for saving my sanity! Makes complete sense now. Should have taken more and better pictures of the disassembly 10 years ago. Funny how you think you don't need pictures because you're going to get right on it. Then before you know it...10 years have gone by and you're asking dumb questions like me. Thanks again everyone!
