Strip back the outer insulation on one end of the cable, so you've got about 1.5" of wire to work with. This will be the "male" end of the cable.

Untwist each of the four pairs and arrange them as follows:

1 - Orange / White
2 - Orange
3 - Green / White
4 - Blue
5 - Blue / White
6 - Green
7 - Brown / White
8 - Brown

This follows the 568B wiring schema which is what I always use when wiring up patch cable. To make normal 10/100 base crossover cable one end needs to be wired 568B and the other end needs to be 568A. Basically what you are doing is swapping the orange and green pairs from one end of the cable to the other, hence the term crossover.

**Note that for gigabit ethernet you will need to cross the blue and brown pairs as well.

Trim back the excess wire, give your self about .5" to .75" to insert into the Cat-5 plug.
