Where can I find this kind of 14-wire BMS connector?

[Pacto]

It has 14 wires (13 positive, 1 negative) with a plastic clip. Anyone know what this is called and where to find one?

I was in the processing of replacing the BMS but messed up when disconnecting this connector from the old BMS. The problem now is that somehow there is continuity between every pin of this connector. All the wires are still clearly separated (as are the visible parts of all pins) so I'm guessing something must have melted inside the plastic? Any help would be appreciated.

messed up

Yes looks like you cooked it.

Any numbers or words on the connector? BMS manufacturer / part / model / number?

Today I will copy and paste.

There are lots and lots of connector types used in the ebike industry, so many that it would be a very tall order to try and list them all. In our business, we focus just on aftermarket conversion kits and have tried to keep the connector styles down to a well chosen minimal set. This page...

BMS Header​

The battery management circuit in a lithium pack needs to connect to all the individual cell tap points, and this is normally done with a single row 10 - 15 pin header connector, which can vary in pitch from 1.5mm to 2.54mm. It's usually possible to find compatible pins and plugs from digikey or other electronic parts tendors, manufactured by the likes of JST, Molex, Tyco, etc.

If I got this right the wires are still connected to the cells?
In that case it is impossible that all the pins are connected to each other in the connector if there is voltage in the cells.
You would have a fire.
But of course there will be a connection between all the pins trough the cells.

All the wires are indeed connected to the cells. I did remove the negative wire from the connector.

It looks like I reversed the polarity of the multimeter leads when testing; there's no connection displayed when I use the correct polarity leads on each pair of pins, so does this mean the connector is still good?

Define 'good'. Looks pretty molten to me. But probably not shorting the wires, yes.

Why are you checking continuity on wires that have voltage? This could damage your multimeter.
For future reference, you should only measure voltage with the volt setting on your meter and not continuity.

Sounds to me like you're not using the multimeter correctly, or don't know how to use one properly.
Putting the black probe on positive will only cause the voltage displayed to have an - in front of it.
Like -3.77 instead of 3.77.
