How can I control multiple points of a cloth sim? I'm following a tutorial for a crate design, but I wanted to add some extra flair to it. I thought it would be cool to animate a ribbon of wires as it slides open. It's almost done, but I can't figure out the last bit.

As you can see, the ribbon isn't pinned down on the opposite end, so it just slowly slides out of place. I found this answer on in another post, but I couldn't figure out how to apply those techniques to my test scene. I'm still pretty new to Blender, so I'd very much appreciate any help/advice. Cheers!
Instead of constraints you could hook the left extremity to an empty and add the vertices of the opposite extremity to the pin group. Put the Hook modifier above the Cloth modifier. In the Physics properties, increase the Quality Steps up to 20 to make it work correctly. You don't tell about what's supposed to happen after the last picture of your gif, does the extremity on the right stay still?


Even simpler, you could give up cloth simulation and use a Curve modifier:
