That looks like an Adobe P2-911 plug and it is proprietary. There's another version Adobe made (I believe it's for the 230v motors) that has a 5th round pin. The flat bladed terminal is for keying the connector so it can't be plugged in upside down. You should have a 115v cord with 2 hots - one for high speed and one for low speed, 1 neutral, and 1 ground.
This is what I'd do: Leave the terminal of the capacitor which is connected to the supply as it is. The other terminal is connected to one end of the winding. This needs to be disconnected and connected to the other end of the winding.
