I have a hard plastic vacuum line that comes out of the right harness that came from the front of the engine and has an elbow on it. Whats it for.

That goes to the HVAC system inside the car and should connect to the check valve. I'll take a pic of my car tomorrow.

But that harness goes to the front of the car. Then the plastic hose pops out. Shouldnt it come from the inside of the car?
