    What is 4788 DC Accessory #2 "Head Water" Circuit???

    I've been tracing wires on our boat, and am puzzling over the DC accessory #2 switch.

    Accessory #1 is the flybridge fridge, and Accessory #3 and #4 were clearly added by a prior owner - and I have traced them out.

    But accessory #2 is a mystery. It is a brown/white wire with the factory wiring label tag saying "Head Water".

    But what on earth is "Head Water"???

    It is clearly part of the wire bundle pulled by the factory - do any other Bayliner 4788 owners have this? What is hooked up to your accessory #2 circuit?

    Help solve the mystery!

    Pretty sure it is for the head water pump for the std electric heads NOT vacuflush which was an option. It is in the 4788 owners manual....
