Sorry Seamon I don't know of any drawings available. The wiring harnesses were made by Lorco Marine long out of business. The harness ran from the panel to the hull deck joint at the back of the galley aft to the stern light along the hull deck joint. Forward along the starboard side at the hull deck joint feeding the cabin lights that were mounted on the decorative hull deck joint covers there was a drop for the bilge pump at the main bulkhead on the starboard side, the harness went forward to the nav. lights then back down the port side feeding cabin lights and the mast lights were fed from the port side at the main bulkhead.
The battery was located under the step at the companion way.
You can probably find a book or two on this site about 12 volt wiring for correct wire sizes and circuit protection.
