Hi, I am replacing the original motor on a pentair whisper flow WF-26 pump. The new pump wiring looks different. I need help with wiring the new pump. First pic is the old pump wiring, the next 2 are from the new pump. Can anyone help me wire it?

Stand so the pics line up with the diagram. The positions of L1 and L2 don't matter but I'd go black to black just because. My brain wants to put the green one on the middle lugs but it's specifically left off the diagram so it likely goes to the motor housing. It should be listed / labeled in the manual.
Whats the part/model # of the replacement? @1poolman1 might know it.

Replacement is a B2854V1. I think it's hot wires into the terminal and then there is another threaded area near the terminal block. that may be missing a screw. I'm thinking that might be the ground. I'm going to get a screw for it now and try it that way.
As @Newdude above. The 2 outer spots get the red and black and NOTHING in the middle as that's where the motor windings configure 240v. The green goes to a green screw on the motor frame which is somewhere close by.
The ground location should be labeled on the motor or in the manual. It could be missing the green screw as you said, or this one kinda looks suspect with multiple washers.
@InyoRich is around this morning. Maybe he can get you a quick answer.

I agree with Newdude's post above - black to black and the red wire to the opposite terminal with the white wire (though it also triggers my OCD). That's a pretty odd wiring terminal block for a pool motor. Be careful to be sure that the screws don't penetrate the plastic block and short out anywhere.
The motor you have looks like a cheap Chinese knockoff motor from Amazon.
A lot of top search results are Chinese fake products with the same model numbers as the known brands.
The Century B2854V1 motor has a different wiring terminal plate.
Can you show the link to the motor you got?

Ok I have it working now. I grounded to a threaded hole that was missing a screw right next to the terminal block. Here’s how it ended up. And yes I’m totally going to reattach the terminal block to the stand. And connect up the conduit to waterproof it all. Thank you all so much for the help!!!
It's definitely a cheap Chinese knockoff motor.
The label does not show a make or model number or a manufacturing date.
Don't be surprised if the motor fails fairly quickly.

The label says thermally protected, but there is no thermal protection, so if the motor overheats, it will probably just burn up the windings.
Also, notice that there is no UL safety testing done on these motors, so you have no assurance that the motor is safe to use for any purpose.

Yeah I really wanted to see if this repair was something I could do. Maybe I’ll get a year or two out if it 
These Chinese knockoff motors are definitely thermally protected during shipping while at sea.
It’s always a bad sign when a manufacturer does not put their name on a product.
No manufacturer name, no model number, no serial number, no manufacturing date.
It’s like going to the supermarket and buying a can with a white label with only the word “FOOD” on the label.
