Yaris IA OEM Jack Point Adaptor - how is that used?

[djc664]

In my trunk, I have a foam insert around the tire. It has this small black cylindrical tube, with a flanged top and two little "wings" sticking out and down from opposite sides.

The owners manual has NOTHING on it but a note that it's called a Jack Point Adaptor...

Where's the Jack Point? Who knows! I can't find any kind of service information for the 2017 (which is what I have) or 2018 even for Yaris IA. I know it's a Mazda 2 engine, but none of the diagrams I've found match what my car looks like. :(

No one seems to know what to do with it, where it goes, how it works, etc.

Yes, I know how to jack up the car with the pinch welds and all, but now this is the principle of the thing. lol

Hoping SOMEONE knows how it works... Halp! :)
