where is Water pump inlet connection

[ashcan]

In my 2016 Bambi Sport manual, the 8th step for winterizing is- "Disconnect water pump inlet connection and turn the pump on...". There is no visual to identify where the inlet connection is. I'm wondering if it's the brass plug near the pump (below dinette seat) but since I'm a newbie at winterizing I'm hesitant. Thanks for any advice here.

What they mean is, unscrew the hose from the fresh tank where it screws on to the pump. On my 25FB, the hose is white and flexible, and the connection on the end is plastic. I don't have any brass plugs or parts in my plumbing.
