Bill,
I have some generic diagrams on my site under "Marinette" and perhaps those will help. My dual-station M had very little of the original wiring because of the engine swap, they installed the Perkins harness that came with the engines.
What I have posted is taken from diagrams that forum members have sent me. But if you post specific questions, you will get a ton of help from forum members.
If you look under "Tin Lizzie" you will find diagrams for how I have wired my boat. None of the engine wiring and a lot of the other wiring are not stock.
