It doesn't really matter which vacuum line you use, as long as it connects directly to the intake manifold. That line on the left in your picture goes to the PCV valve. The other big line on the right goes to the brake booster. I would use the brake booster line and leave the PCV hose alone.

Wouldn't using the PCV line help clean out any oily gunk that may have built up in there? Edit: Also, wouldn't that help the Seafoam follow the same path as the PCV gunk and better clean up deposits resulting from such?
