Color Codes for 8P8C RJ-45 Ethernet Plug:
Eight-conductor data cable (Cat 3, Cat 5 or Cat 6) contains 4 pairs of wires. Each pair consists of a solid color wire and a white and color striped wire. Each of the pairs are twisted together. To maintain reliability on Ethernet, you should not untwist them any more than necessary (about 1/4 inch).
The pairs designated for 10BaseT Ethernet are orange and green. The other two pairs, brown and blue, are unused. The connections shown are specifically for an RJ45 plug. The wall jack may be wired in a different sequence because the wires may be crossed inside the jack. The jack should either come with a wiring diagram or at least designate pin numbers that you can match up to the color code below.
Crossover Cables:
In order to make what is commonly referred to as a “Crossover” cable one must change the pinout connections on ONE end of the cable. If you do it on both ends of the cable you have crossed-over the crossover and now have a straight-through cable, albeit a very non-standard one. In this case two negatives do make a positive.
You need to make a cable where pins 1 & 2 from one end are connected to pins 3 & 6 on the other end, and pins 3 & 6 from the first end are connected to pins 1 & 2 on the other end. Pins 4 & 5 and 7 & 8 are unchanged.
The two ends look like this:
Standard End Crossover End
Pin 1 Light Orange Pin 1 Light Green
Pin 2 Orange Pin 2 Green
Pin 3 Light Green Pin 3 Light Orange
Pin 4 Blue Pin 4 Blue
Pin 5 Light Blue Pin 5 Light Blue
Pin 6 Green Pin 6 Orange
Pin 7 Light Brown Pin 7 Light Brown
Pin 8 Brown Pin 8 Brown
The following is the proper pin out and cable pair/color order for the “crossover” end.
| Pair#2 is connected to pins 1 and 2 like this: | |
| Pin 1 wire color: | white/green |
| Pin 2 wire color: | green |
| Pair#3 is connected to pins 3 and 6 like this: | |
| Pin 3 wire color: | white/orange |
| Pin 6 wire color: | orange |
The crossover pairs are illustrated in the following diagram: 
Then when the pairs are inserted into the RJ45 plug they should look like this:
