Question How to remove the 220v/110v switch from this PSU ?

[Thorgeirsson]

I have a PSU from a Dell Inspiron 380 SFF PC. I want to repurpose this PSU for my 3D printer but it won't fit. I need to remove the transformer that allows it to switch between 220v/110v. I am guessing that two of the wires going to the board from the transformer need to be crossed and the other two are left open.
I don't know which wires are which. Can anyone help me? Is there a way I can test it to find out?

if you don´t know it, let someone with experience do it. It´s dangerous for your life and your neighbors if you do it wrong, even if it will work for now.

The operative word here is "don't"

Modify your enclosure so this PSU fits, or get a different PSU.
