I have a 2018 Tohatsu MFS50A. I haven't had a tach on it since I got it, and am wanting to add one. I have been told there is a "tach wire" on the main harness, but can't find any schematics online. Anybody done this? Can you use a tiny tach? I have a tiny tach, with the spark plug wrap connection, but it seems this motor needs something different.
