How Do I Connect Purge Valve After Emissions Removal?

Ok. I did emissions removal.

I want to keep my purge valve so I don't have to go with a catch can.

Question is, where do I connect the top part of the purge valve to? I am guessing a vacuum source, but which would be best? I have S5 UIM, IIM.

Thanks.

Top connection goes to a vacuum source. Small bottom connection goes to a fresh air nipple, big bottom connection goes to nipple on oil filler tube.

A nipple on the throttle body that leads to the intake BEFORE the throttle plates. I ALWAYS get these mixed up, so I may be wrong but I believe that all the nipples on the back of the throttle body are fresh air.
