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!

I reckon it's B. Green is the second pair in A, and orange is the second pair in B. If blue is on pins 1-2, as it seems to be going by the numbers moulded in the plastic, and orange is on pins 3-4, orange is pair 2.

(Not an expert, might be wrong, would love to have it explained to me why I'm wrong if I am wrong)
