Finding Damaged Section of a wire in a wall

Lemme explain what he means a little bit more.

Data only travels on wires 1,2,3, and 6, and if you used the 586B standard, it’s the orange pair, and green pair.

Substitute a known working pair for the damaged pair on both ends. Say brown works in your case. The end should end up as follows:

Light Orange, Orange, Light Brown, Blue, Light Blue, Brown, Light Green, Green.

That should work for you, provided it’s only one wire that got jacked up.
