I can't off any specific help since I'm not aware of any such adapter. There can't be that much demand, or someone would offer one. Who knows what will happen in the future though.
There appears to be few standards in the industry, and every bike & part maker does their own thing with these connectors. Unfortunately, if you want to modify a bike, or build your own, cutting & soldering is usually necessary. If you're a DIY'er, the skill isn't that difficult to master.
I use a lot of these extension cables:

They have a male & female end, can be cut in half, and spliced into a circuit.
There are many others out there, but finding the right configuration can be a challenge.
Welcome to the forum and good luck with your project!
