Engine Bay Wiring? 1970 Sea Ray SRV 190 with 165 Mercrusier engine....

[Michaelbluewolf]

Ok, I need to find a schematic or wiring diagram for my old Sea Ray. The wiring is a mess, I would purchase a harness if I could find one that's not as bad as mine. I have searched online with little or no luck.
I have many years as an auto mechanic and have built Late model Race cars so wiring is not a problem. If, I had a schematic or diagram I would be in business.
I would appreciate any help that I can receive.
Thanks in advance for your help.
