What drawing?
Do you need a wiring diagram? That is available on this website, check the page with the O'Day 22 and 23 manual pages.If you need a copy of the original owners Manual, call Rudy at D&R Marine. I also have a copy along with expanded text and diagrams, but give Rudy a call. He is VERY busy this time of year, but is loaded with info. (508)644-3001
