Broke power button connector on logic board

Testo:

Working through an ssd upgrade and the wires popped out of the connector that I believe is the power button connection on the logic board.  Wires are still in good shape, just need to replace the connector but having trouble finding it.  Could also hard wire the wires back to the board, but not sure of polarity.  Is there a way to test? I know the power putton is just a small voltage switch that triggers a relay.

Also, is it safe to power up the device without the screen installed? just for the sake of having to re-dissassemble if I get the polarity wrong.

Here’s my shoddy pic[br]

Sure thing.  I can’t find the little black connector that these exposed wires were harnessed into, it got fairly obliterated during removal.  So perfect solution would be to find a replacement connector and just get these wires back into there the correct way.

I understand this pin out is simple a toggle for the power switch, and was thinking of soldering them directly back to the board.  I was told polarity shouldn’t matter, which is an issue since I dont’ know which wire came off which terminal.

Taking another look tonight, however, i realize its going to be a super tight area to try and solder into.  So I’m basically looking for a coupling solution, hopefully the original part but any other ideas are very welcome.  Pics below
