Hey guys! Got a steering wheel, hub and adapter for my 01 GT-S. I’ve already gotten my steering wheel off, and put the adapter on, but I can’t figure out the hub at ALL.. No instructions were included and I can’t find a video or file to explain how this thing works or is assembled. Any help would be appreciated greatly.

Link to the hub assembly I got:
