Is this wired T568A or B ? Or other ? (alien.top)

Hello! I am trying to replace a wall plate having a small phone plug with an rj45. First time doing this.

The cable itself is a cat5e. On the other end near my switch, there is an rj45 already wired in, so I wanted to check it to know if it's wired A or B, to replicate on the wall plate. But I have this in the photo... 1-2 is blue ?

How should I wire my rj45 keystone for the wall plate ? T568A or B ? Or following the current colors/numbers ?

This a 2016 construction, in Quebec, Canada.

Thanks a lot!

If the 1-8 markings correspond to pin numbers in the socket, it's neither, and also not a suitable wiring for ethernet. It might "kinda work", but probably not very well and it's definitely not proper. The pairs should be 1-2, 3-6, 4-5 and 7-8. Color really doesn't matter much as long as it's the same at both ends (with TIA568A/B being the two most popular way of arranging the colors). That one is neither, with the pairs being 1-2, 3-4, 5-6, 7-8.

As widely suggested by others, remove those jacks and replace with non-silly stuff (at both ends). TIA568B seems to be the most popular one to use, but as long as you follow the same standard everywhere (anything else will be gravely confusing) it'll work.
