Darn Bilge Critters

Good morning all! My good neighbor got "the deal of a lifetime" on a Fun Deck 226 OB with a Yamaha 150 Outboard and I was recruited to assist in make her lake worthy. The fact that it had been sitting for over 8 years obviously was a big concern but, imagine my surprise upon beginning work on this deal...it was the home of wire hungry critters throughout the boat. 

My request is PUH-LEEEEEZE, someone point me in the right direction of a wiring diagram/schematic for a complete rewire will be required. Not to mention all accessories, gauges, lights...etc.

Many thanks and have a great weekend all!
