Hitch retrofit - part numbers

[polityk]

Hi

So I wanted to get all the parts needed for the retractable hitch and I am getting a little bit confused on the part numbers.
There are multiple hitch parts and multiple TRM parts, but they all look the same.

Should I be concerned about particular parts for my 2019 XC60 and the hitch part matching a certain TRM part?

For example what i see on ebay:
TRM: 31346522 31454603 31454602 31454548
Hitch: 32296418 32270814 322708143 32296410

The best is to use the accessory info, you have everything in there.

Foldable Hitch: 32296466
TRM: 32414268 (need a bracket too)
You need also some other stuff like the button for release

basically the only thing you won't need is the software this is where you can use Orbit (I use it)
