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!

This particular port is not suitable for ethernet, it’s for analog phones.
You probably should replace it to be to up spec.
B is the way
Looks to be wired for phone line 1-4, blue, orange,green,brown
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.
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
I would cut off the goofy stuff and install new T568B at both ends.
I know it doesn’t really matter, but to keep in standard with Canada we use T568A
According to the photo of the cover you posted, it’s not even punched down 568A or 568B. Thankfully the pins are labeled on this original picture here, so put it in the same order as an RJ45. Start with Orange stripe on pin one, then do a 568B across the board.
Other. That isn’t either of the standards.
I forgot, here is a photo of the cover for these rj45 plugs.
I was able to track down the data sheet for this exact jack. The blue color of the punch-downs indicates that this is a T568A pinout.
Not A or B , not properly twisted, but it may work. As the colored wires all match each other at the end.
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.
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.
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)
Try to get a probe from an ohm meter on the solid orange wire and use the other probe to find the pin it is attached to. If it is on pin 6 it is 568A, if it is on pin 2 it is 568B.
