Where would this terminated wire go?

Hi all,
I recently purchased a kit from aliexpress to retrofit the RHLS sensor in cars that don't have the correct mounting on the rearview mirror (see atteched images). The kit came with a wiring harness that has 3 wires: red-white, purple-white and brown. Brown is obviously ground. Purple looks like it should go into the bcm (i've seen in another forum that it should go to pin 28 of connector C, screenshot attached). Red is most probably supply, but i can't seem to find anything on the crimped termination. I did not unplug from the bcm yet, so i'm not sure but it looks like it should go to one of the big pins in the bcm connectors or something like that. Did you ever see any crimped terminal like this one?

Edit: in the other forum it's talking about fuse 8, which is the one for light controls and interior lights. The termination doesn't look like it's meant to go to a fuse.

I think i found out. I scoured the internet for hours and what i think it is that the termination is for the cabin fuse box. There are guides online on how to install a new circuit inside the fuse box C (the one inside the cabin near the driver)
