Help wiring my motor

I have a split phase motor 1/3hp I got off amazon. I didn’t realize it was a split phase until I tried to google how to wire it. I need help can someone explain in simple terms what I have and how to make it work. I also figure it’ll move to fast for my extruder so any idea on how to slow it down. Also what is the green wire that’s screwed to it.
First off, the green with yellow stripe wire is a safety earth connection, it should be earthed.
In a split phase motor you have two coils, these are between connections 1-4 and 2-5. It looks like 1-4 is the main winding and 2-5 the start winding (there should be a capacitor in series with this winding, may be hidden inside the case).
Note that I’m not familiar with US wiring, but it looks like you should connect what I believe is called the ‘hot’ wire to pin 1 and the neutral to pin 4. Then if you also connect 2 to 1 and 5 to 4 the motor will spin in one direction, 5 to 1 and 2 to 4 it will spin in the other direction. (The connections are left permanently in place).
BE VERY CAREFUL WITH LINE POWER! Note the warning on the motor and insulate/cover the terminals so you can’t touch them.
Thank you for your help. I have a much better understanding now 🙂
