While cleaning out some un-necesary stuff under the hood, i noticed i had a hose connection coming out the rear of the TPI runners on the Driver side. The connector (to slip a hose onto?) is about 1.5in-2in long and super skinny. Evidently its not hurting me to bad, but would really like to know what it does and hook it up if able to!

 

Deleted response. Wrong hose.

 

hard to tell from how you describe it. where exactly is the connector going to? just somewhere under the plenum? I am guessing it's for the cruise control/vaccum reserve.
Only connector that is over there comes off the plenum and is the vaccum for the brake booster.. but the car would not run right if it was open. It's not skinny more like a finger width.
Ther should't be any connectors coming from the back of the runners, as in actually connected to the runners.
Can you get a picture of it?

 

There's only 2 vacuum ports on the drivers side. It's either a the brake booster which, like stated above, is a pretty good size port. There's also the PCV valve inlet between the first 2 and last 2 runners.

 

I will have to take a picture of it today, but i know that it is not the Vavle post, and dont think it is the brake booster either unless the hole opening for it is only a pin wide. this is really confusing, but i just want to get it plugged up.
