I am using ON-Q RJ45 jacks on the other end of the CAT5e cable and my tester showed pairs 1&2 and 3&4 reversed when using the above diagram. I had to swap Orange&Orange/white pair with the green&green/white pair to correct the problem Thus:
1 White/green Blue
2 Green Orange
3 White/orange Black
4 Blue Red
5 White/Blue Green
6 Orange Yellow
7 White/Brown Brown
8 Brown White
