Sealand Tankwatch 3 problem
 

1998 Formula 280 ss. System worked last year. This year lights would not turn on. When I went to remove panel in head I accidentally pulled a black, yellow & white wire out.

Which number slot do I screw that wire back into?

Last question I have on the fuse panel for shore power & 12v in the cabin closet. I have a switch for waste system. What does this do? Toilet is a pump handle toilet & sewage tank is pumped out with a pump? Was this in there not hooked up also used in a bigger boat or does it somehow pump the toilet overboard? Thanks for the input.
