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!

    Pull the wires, start jumpering pairs and meter it out at the other end. You will be able to figure out what the pin out is as the plug end and then set it up however you choose. But the other suggestion about just cutting both ends and wiring as B is the best. Just giving you an option if you don’t want to cut the other end
