Welcome to TFP.

What model motor are we discussing?

Show us pictures of the motor data plates on your old and new motor.

Old motor looks like a two-speed motor that was wired for one speed only. If the new motor hasn't been damaged by the way it is now wired, and is a single-speed motor, move the wire from terminal 2 to terminal 4 and it should work.
It looks like that "new" motor is a used motor based on the condition of the spade terminal at position 4.
 
Thank you Very Much!
I will try your suggestion

The new motor looks like a Chinese Generic.

There should be a label with a wiring diagram.

You might have to translate from Chinese.

I found this from a different motor and it was not much help.

将电源线与泵电机的电线连接起来,然后连接到电源,电机就可以正常工作了。

Old motor was a 2.6 total horsepower motor. New motor is a 2.2 total horsepower motor based on all the pictures of the rating plate on E-bay of the motor with that number. It won't last long if the impeller isn't changed. The new motor is for a 1.5hp full-rated, 2hp up-rated pump, a WFE-6 was the full-rated version. You have a full-rated pump, a WFE-8.
The impeller on your pump is for a full-rated motor. It will overload the new motor.
The CMP 25305-129-000 impeller is a good alternative to OEM and costs about 1/3 less.
