Ethernet RJ45 568A and 568B Wiring

Drag and drop the colored wires to create either a T-568A or T-568B wire ending.

T-568B is the most common type of wiring and is used on both ends of a straight-through RJ-45 Ethernet cable. On crossover cables one end is T-568B and the other is T-568A. The difference between T-568B and T-568A is that pins 1 and 2 are switched with 3 and 6.

If you need help before starting you can see this RJ-45 wiring diagram.
