How can you identify a miswired pair in a copper cabling system using a wiremap?

Wiremap testing checks that each conductor runs to the correct pin at the other end and that each twisted pair stays paired on its designated pins. When a pair is miswired, the test results show incorrect pin-to-pair mapping: the two wires that should form a single pair end up on pins that aren’t a proper pair, or one wire from a pair lands on a pin that belongs to a different pair (a split pair). The wiremap readout will reveal these mismatches, making the miswire obvious. Other tests, like insulation resistance or jacket color checks, don’t verify how the individual wires map to pins, so they won’t identify this issue. By confirming that every pair’s two conductors occupy the correct pins, you can identify a miswired pair.
