Pin 2 - NC (i.e. not connected), all other You can move, as You need - pinout for PS/2 is for example here: https://hw-server.com/connection-over-ps2-port

See those little gold bits in the connector? Those are the latching tabs of the contacts, you press those with a jewelers screwdriver, pull the contacts out of the shell and arrange them however you want.

I'll move the plastic stops, with a needle or little screwdriver and pull contacts out of the shell.

You can also use jumper cables such as these to hook up the connector to the pins on the motherboard, one by one.

This is assuming you know the pinout for the motherboard and for the connector on the bracket as well. The latter can easily be determined using a multimeter via continuity testing.

About the one I linked above, are there any good sources for them anymore? The sites I did find them on want to charge insane shipping prices ($10-$25) for something that can easily ship in a bubble mailer.

My spares bin..😉

You can usually find those cables in places that sell Raspberry Pi and Arduino accessories.

I buy them locally, but I posted the Amazon link since it's more convenient for most people.

Did manage to find one for under $10 shipped within the US. Just need to double check the pinouts when I actually get it in.

This video made by a fellow Vogons user might be helpful.

Above all else, be sure to properly match the bracket's connections to the corresponding motherboard pins, otherwise you may risk damaging the board.

If I understand correctly, You need connect wire from bracket to board so:

The layout of the female PS2 connector (where you plug in the mouse) is always the same. But the connector which goes from the bracket to the motherboard can have different layouts even if it looks the same visually.

That's why it's recommended to do continuity testing on the bracket (as shown in the video above) in order to correctly identify which wire carries which signal, before attempting to hook it up to the motherboard.

I always do continuality testing on the bracket and then rearrange pins in the header to make these bloody things work. And if you are stuck spending $10-$20 on delivery, order 3 or 4 of them to make it worthwhile.

And yes, if you are not careful, you could cook things. I almost cooked one of my PS/2 optical mice this way .... something got nice and hot and started to smell like electronics about to die. I suspect that one of the chips had reversed voltage and the ESD protection diodes inside the chip were transmitting power and heating up one of the ICs, as fixing it properly resulted in the mouse working correctly as it should, despite it's near death experience.

Yes, I know - that's why I marked the pins from the board and from You has a usefull link to the video, how to pull contacts from the connector, all that's left is to check them and assemble them correctly in the connector to the board, that´s all.
