I’m trying to fix my daughter’s electric scooter. The company sent me a brand new motor, out of warranty, however the adapter is wrong (see pic). I’m thinking I’m better off swapping the couplings rather than cutting and splicing, but I don’t want to destroy them - what is the best way to remove the wires? There appears to be some sort of yellow wax/paste holding the wires in.

The perspective of this pic makes it look like you have the cutest little crescent wrench and screwdriver
There is a tiny little tab on the silver pins, bend that flat and you can pull the wires out and put them in the other connector.
That being said, just cutting and splicing would be the easiest option as this pins can damage easily.
That would not ally be the answer, but if you look carefully it seems like the manufacturer also added some sort of glue/solastic to the connector (probably to help mitigate vibrations) so that’s going to be a no go.
If I were OP, I would buy a connector kit (on Ali if they don’t mind waiting, at a local electronics shop if they have one available, or on the Bezos Fun train if they don’t and can’t wait) and just make a new connector.
Cut off the connector you don’t need, you can leave some wire in case you ever need it for some reason, or you can cut out close and just toss it.
Cut off the one you do need, with lots of slack, and then splice on to the freshly cut wires (hopefully with solder and heat shrink.)
Connect it up and move on, hopefully you’ll never need to think about it again.
If you still really don’t want to do that, you can try pushing the pins out. This might help: https://youtu.be/0G7iIwfuaJ8 and this https://youtu.be/BbXX32X-Hkc
The paste might be dielectric grease to keep moisture out.
Here’s another one that does both male and female on small connectors https://youtu.be/59gWZS92zgc
If you’re certain that only the housing of the connector has changed from old motor to new motor, and each pin inside the housing is the same, then I’d recommend trying a heat gun to melt the waxy adhesive, followed by poking around with a tiny flat screwdriver to unlatch the pins.
But if it were me, I’d just splice the wires. You will need heatshrink or at least electrical tape, a soldering iron, and solder. A good splice can easily handle more current than that little connector.
Pins are glued, they won’t just come out. There are tools to remove those pins and you can basically make your own, it’s basically a thin flat piece of metal you shove into each channel to move the retaining tab out of the way temporarily
https://a.aliexpress.com/_mMa3SwF something like this, the ones I have are different, but you can makeshift something in a pinch
But again the adhesive will mean this won’t work unless you cut/remove it. Also are you sure the only thing that’s changed is the connector? The pinout may have changed, the board you’re connecting to may have changed, etc
I can’t tell but try looking up tutorials for removing molex pins.
