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!

Other. That isn’t either of the standards.
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.
Idk wtf this is but if 1 2 on the bottom is indicating the pins, this is all messed up
This is type A .
Belden DVO connector BIX
the pairs are in order blue/orange/green/brown Standard phone order
Unless you’re using hardware from 30 years ago it shouldn’t matter if you end up making a crossover cable or a straight through cable.
Couple issues here… you tx on 1&2 and rx on 3&6… if you need a xover then you flip one end… that being said the colors are wrong… they are just punched in order in the pic which is what you’d do for phone. The pairs are wrapped at different rates which matters from an Ethernet standpoint. So re punch WO O WG B WB G WB B and flip the tx/rx on one end of you need a xover (but you prob don’t)
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.
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.
I forgot, here is a photo of the cover for these rj45 plugs.
Not A or B , not properly twisted, but it may work. As the colored wires all match each other at the 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
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.
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.
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)
Type T568A won: I am currently typing on a PC wired into the new keystone! Thanks a lot everyone for the help, every comments have been very useful.
Here is the final punch for the curious: https://imgur.com/a/Z5KSvPu
My first one ever, I am super excited. It’s not perfect but it works for my immediate needs.
I will probably redo the full patch panel + wall connections in the future, inspired by the great stuff shared in this sub :)
Thanks again!
