This switch (the blank) is in the day head. All three that are marked Head are for lights an of coarse vent is vent. The blank is a switch with wire connected to back. I cannot find anything that powers on/off with this switch in day head or guest cabin. Any one with a 500da have this switch ?

Probably just a blank switch that's not used in your boat. The wire is likely "pre-run" back to the breaker panel.

Agree with LD. I bet it might be an extra prewired for ground or...maybe for a macerator? When they used to be popular.
