40el72 Johnson electrical

[Kylebellis]

Got a old Johnson on the weekend it's
In decent shape turns over greats with near perfect compression, but I have a few questions about wiring my specific year isn't in the wiring guides offered here... There no spark.... What is the small switch under the flywheel
That looks like a square button, the wire
Was totally corroded . Also would the main harness have some thing to do with it if a post inside the male plug was loose? Thanks alot

You might look for an OEM factory service manual.
