Mystery vacuum line around cruise control box

[tahi]

As I was checking my vacuum lines around the cruise control unit (left side of teh engine compartment). I unplugged a vacuum line and I cannot see where it was plugged.

Here's the sheme : one line is coming from the other side of the engine compartment (plugged on the engine). Close to the CC unit this line is plugged on a connector (apparently equipped with a bypass system). This connector splits in two lines.

One of those two lines is plugged, but I don't know where does the second line is supposed to go. This mystery line is about 5 inches long.

If someone does have an idea or a vacuum chart for this area of a 98 V6 blazer it would be great.

one line should go into a vacuum ball mounted on the hood and the other part w/the bypas valve (t's off) it goes onto a hard plastic line that goes into the firewall under a harness on the drivers side under the CC unit

Thanks for your reply. I spotted the hard plastic line that goes into the firewall and the vac line is plugged on it but I cannot see the vacuum ball monted on the hood. How big is this ball?

My other question (sorry for being that stupid)is : what do you mean by t's off?

As you probably figured out, english is not my first language so I got some severe lacks...

he means it goes into a T fitting. the black ball may be in the front fender on a 98 tho.

its a box in side the fender or a ball the size of a softball mounted to the hood 98 up should be inside the fender right at a 90' degree from the fire wall
