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!

Neither, T568A start with striped green in the first pin and striped orange on the T568B.

Jacks don't necessarily have the punchdowns in pair order, they "fix" the order in the traces between the punchdown and the socket. This makes it easier for an installer to just go pair by pair.

u/DiscontentedMajority posted the datasheet, this punchdown order is correct for this jack for T568A. Always check the datasheet or instructions, or verify with a meter.
