I was changing my ABS Module on my s70 and while pulling the air breather box out noticed two vacuum ports on the box. A white line was attached, but I found a thin black line unattached under the box. Can someone help me find where the second vacuum line (black in color) attaches on the engine from the port on the air breather box? Thanks.

 

Looking at the breather box first clip right under that, looking at the positive cable of battery go forward about two inches in a tight area.
