How To Swap Couplings? (sh.itjust.works)

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.

EDIT: Thanks to all who replied; I’m going to try and splice the wires. Solder should be here tomorrow, so hopefully she’ll be up and running in no time!

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.
