1988 Carver 4207 aft Cabin wiring

[bvcllc]

My 1988 4207's bow bilge pump, bowhead shower, ac pump and other wiring under the floor in the galley area was switched, rigged, spliced, diced and rerouted with some wires not even connected by an earlier owner and an emergency quick fix by a shade tree electrician. I can't find a wiring schematic for this area and am completely befuddled. Will someone be kind enough to send me a pic or two of their setup if you are happy with your rig?
Thank you in advance.
