You're welcome, Jason.
Jimmy's information is some of the most reliable, because he has worked for so long with many of the Aerus (Electrolux) models, so I yield to him.
I also appreciate that he's always respectful and doesn't try to start or participate in arguments with others who give incorrect information or who have different opinions as he has once again proven in this thread (thanks, Jimmy).
I mistakenly took the hole of the cord 'cleat' (Aerus's term) to be the hole for the cord; so, yes, your cord is original. Sorry about that.
I think the cord was first designed to be hard-wired on the Genesis 1572F, which was introduced c.1990 and was equipped with the 9.5A motor.
In case your aunt has a need for a Sidekick for cleaning hair from the furniture, here's a link to the Discovery III Adapter Kit (service number 43542) currently listed on eBay:

Although its casing is taupe to match the DIII 1572E, it would still be compatible with the RS. Fyi, I have seen light sand gray ones, too, that would match the RS and others. In fact, I had an opportunity to purchase a Discovery Advantage 1572E with one attached at a thrift store, but I passed on it. I ended up getting a Genesis LXe 1717 another time, though, so I'm not disappointed.

I neglected to mention before that my GLXe does have the 'dreaded' ponytail cord; but since someone had cable-tied the first part of it to the handle, it works just fine.

Ideas to help make an Aerus (Electrolux) upright a top performer:
1) Remove the brush roll to clean the bristles, the roll, and the bearings. Replace if bristles are short, too soft/deformed, or bearings are gummy.
2) Clean out the inside of the nozzle and brush motor.
3) Check air duct for holes or cracks and make sure it's secure at both ends. Replace if necessary.
4) Add a foam filter (if none is present) in the bottom of the bag compartment to prevent any contaminants from a leaky or broken bag to enter the suction motor. If there is a filter, make sure it's clean.
5) Avoid using the blue Home Solutions bags due to leakage issues. I use 4-ply aftermarket ones that have better air flow and contaminant retention performance.
6) Always ensure that the bag door is closed tightly.
7) Oil the detents and wheel shaft.
8) Check/tighten nozzle, bag door hinge, and handle screws.
9) Clean and lube suction motor.
