Hardware connect power block not working

[Chris01]

Hi!

I have a question about my ps4 where i did put thermal paste on it.

Everythings did fine but now i'm stuck with the power block.
When i am trying to put back the little white connection with wires on it i can't connect inside the power block.
My ps4 is the first one that came out.

Does anyone have a solution for it?

Thanks in advance!
