We have a U.S. Built 2009 B43 2-cabin (Hull #59). While working on another problem (the aft shower drain pump doesn't prime very well), I noticed an unused wiring harness under the aft head sink. The harness is near the manual shower pump switch, has yellow and brown wires, and a 15-amp 12v fuse. We have a macerator installed, so it probably isn't for that. Maybe its for another electric flushing system (one is more than enough for me). It doesn't seem to appear on the schematic. Any ideas?

There is also a large bundle of the standard red/black wires hanging down in the back of the control panels. It could be anything, but obvious, that is.

Do you have an electric toilet in the aft head? If not it's probably for that.
