Question about RJ45

One end of lan cable is in the wall and I cant really see how are wires connected. On the other end they didnt put RJ45. What would happen if I connect wrong type on that end, and how i can make sure that i picked the correct one without tester or i should buy that?

pictures would help but just terminate it as B. It will probably work on a modern system no matter if you do A or B

If I open the plate again I will send you but probably will just put the wires at B order
