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!

    Can’t tell without a legend as to what pins are mapped to what punchdown. That would likely have come with the jacks when they were purchased. Look at the other end, and then just wire your new wallplate according to that, or trial and error, as you have a 50/50 shot. Just don’t trim your ends until you test it, and leave a touch of extra cable, so you can just pull them out and punch it down the other way.
