Go to the National Forum below and search that. There is a place where there are DC & AC schematics, fresh water and sewer schematics posted. I know there is a 2005 Sea Breeze, as I supplied ours to be posted. I forgot how to get to them, but just look around a while, and I'm sure you will find them.
