You have it correct for one direction.
( + ) 1 and ( - ) 4 to power supply. 2 and 3 connect with wire. (It does not matter which is positive and which is negative.)
Edit. When I first posted I made an error. This should now be correct.
For rotation in the other direction link 3 & 4. Apply power to 1 & 2
I want to test to see in wich direction motor is rotating from post #21 if is not rotating how I want then I will connect to other position 1-2 to power supply and 3-4 connect with wire
