@Kathy_J , welcome to the Community.
I can't find a video about replacing the Space Bar, but here is one that shows how to replace the Tab key with the same setup as your Space Bar:
If you place the Bar the way it should be installed and turn it to the side like is done in the video. it should be easy to get it installed properly. It looks like the left side facing is the right side of the Bar when in place. The wire will slip into the slots on each end of the Bar and then into the four clips at the bottom of the space in the keyboard.
