I do think that the metal cap on her arm is probably the answer. They probably connected her arm's nerves to that cap, and the cap allows her to easily connect her prosthetic arm to it and acts as a way to connect the prosthetic with her nerves without actually having to attach her nerves to the prosthetic.

This is actually a smart idea because, if the prosthetic gets damaged, it has to be removed and repaired, and if her nerves were attached to it, that would require detaching the nerves before removing it. But with the cap, they can simply take the prosthetic off, repair it, and put it back on, no surgery required. Plus, if technology advances and they come out with newer, better prosthetics, she can easily switch out to a new one, so long as the new technology is still compatible with the metal cap.

Remnant does have some really advanced technology that may not make sense at first glance. I mean, we've been told that the little metal plate on Ironwood's forehead is actually a device that wirelessly allows him to control his robotic half.
