What does this connector connect to?

[Quaylon]

Hi all.  I'm in the middle of a water pump replacement that has expanded to include a bunch of other maintenance items including the replacement of the AOS on my '99 C2 convertible.  Once I removed the intake stuff and the alternator I finally got the AOS out.  Now that I'm ready to start re-assembling, I have found 2 things that aren't connected to anything.  First up is a 2 conductor electrical connector that I don't recall disconnecting. The wire joins the wiring harness on the left side of the engine just to the outside of the dome shaped vacuum tank. I've included 2 photos of the connector. My apologies for the quality.  I do't know if it's important, but I can see that the inside of the connector is green.  My guess is it's the dust seal and not important.  Any hints as to where I should look for a place to plug this in?
 

Secondly, the "Y" connector in the vacuum circuit has 1 missing line and the leg of the "Y" has been plugged. It looks like someone purposely did all of this.  The last 2 images show the "Y" connector as I found it.  Has anyone seen anything like this?  From the parts drawings I can't determine where the missing vacuum line would go.

The car was running great with no CEL etc. Can/should I leave one or both of these as they are? I'd really hate to put it all back together only to have a problem and have to take the intake and alternator out again.

 

Thanks in advance!

could these be part of the optional mechanism for release of the speed-brake parachute in hard braking from over 125mph?

judgejon, I think you nailed it.  Now to see if one is available on eBay:-)
