Where is the location of the A/C evaporator drain under the car on my Mercury Sable.

My passenger floorboards and carpet are soaked after it rains (most of the
time) but not all. It also travels to the back. Checked the Sunroof drains and
passenger side windshield, which seems to be fine. Took glove compartment
off but not sure which hose is it, crawled under car and took a few picks but
want to make sure I find the right location before I start poking a pipe cleaner
and  if compressed air up the wrong thing. Picture attached. Thank You!
