I keep a roll of blue masking tape and a sharpie on my boat at all times. Labelling things prior to disconnection makes life easier. Especially if you end up disconnecting something in Oct and reassembling in April. (Lesson learned).
If I understand it, you have the drain hose from the shower sump and the raw water cooling hose for the A/C??
Pour some water down the shower drain and turn on the pump, whichever hose the water comes out will identify both hoses.
