Intake Vac line connection 98 XC 70 need help

[Chef Rhody]

Hello Volvo people,

I have asked before and was unable to get a response. So I thought I would include a picture to assist you. After a top end rebuild I was unable to find the location to attach this Vac line. I comes off the intake manifold, right side below and to the right of the fuel return line. I sort of remember that it went around the right side and to the back (exhaust side) near the tubo but cannot seem to find any unattached port to connect it to. Ever seen this line? and where does it go. Thanks in advance,
Chef
