Sun Roof Drain Location S60 2012

[BrunoGora]

I need some help locating the interior side of the sunroof drain tube on a 2012- S60. I need to attached the drain hose to it. I have removed the wipers and trim to locate the exterior side of the drain tube, which drains into a plastic tray located on the outboard side of the battery. I can see the outboard side of the tubes, pass a plastic line through it and find the line on the interior at the corner of the dash. I can't reach the drain tube from the interior. Need Help. Thanks.
