I am still not following you. I get the fact you can trace the pins from the original io header to the power connector switch. Now you know what pins on the mother board control power. I am not following when you make the transplant. how do you connect the new power switch connector which is a different size to fit into the from the new case to he motherboard male pins on the FPCONN header.

You remove this plastic part, so you only have the pins inside of it.

Ok I pulled the cable out and took a picture. Harness Part #(842941-001). The only way I see this working is cutting the end of the power sw plastic housing from the new case shown in your picture and cutting off the proliant switch from the original harness (black and white wires). This way the switch works as intended. I am sorry for sounding dense but I am still not following how you want to wire this up.

I guess you COULD do that, but then you would probably void your warranty.
The way I've done it, is to remove the plastic housing I showed above, and mounted it like this in the new case:

a picture is worth a thousand words. I see now. how did you get the pins out of the POWER SWITCH plastic housing? I can put some heat shrink around the pins so they dont short.

nevermind, I see the clips you need to pull back to release the pin.
