How to Make an Ethernet Crossover Cable
An Ethernet crossover cable connects computers together instead of a hub, network switch or router. Making your own Ethernet crossover cable requires some technical know-how, but can be accomplished by the determined novice. While it is much easier to buy an Ethernet crossover cable, get a great deal of satisfaction out of knowing you made one yourself.

1
Get a length of network cable that easily reaches each computer. Double check by following along the baseboards to each computer to ensure you really do have a long enough cable. Allow enough extra cord to service the computer without having to unplug the cable.
-
2
Purchase RJ45 cable connectors. Ask local computer stores if they have any left over from recent network installation jobs. Have at least 3 in case you make a mistake.

Remove the RJ45 connector from one end of the cable. Strip the cable insulation and trim the internal wires to the same length as the ones inside the connector you cut off. Ensure that each wire is of equal length.
-
4
Find someone to hold the cable and connector while you secure the connector cable lock. Put all wires into the proper holes and make sure the wires are pushed completely into the connector. Use a screwdriver to tap the connector cable lock slot in place. Light pressure should do the trick.

Have the helper hold the RJ45 connector while you seat the brass wire conductors into place. Tap the brass conductor down with a screw driver just below the plastic ridge. Look at the removed connector to guide how deep to seat the conductors.

To make a crossover cable, you use two different wiring orders for each end. With the plastic tip of the plastic RJ-45 connector facing down towards the floor: On one end use the standard color order: White/Orange-Orange,White/Green-Blue,White/Blue-Green,White/Brown-Brown For the other end, switch the location of the orange and green pairs (so you switch white-orange with the white-green, and switch the solid orange with the solid green giving you the color order: White/Green-Green,White/Orange-Blue,White/Blue-Orange,White/Brown-Brown). The Crossover Cable allows you to connect two computers directly together by their network cards without using a hub or switch. This type of cable is also needed when connecting a hub or switch together that do not have an uplink port. -

How about posting the color order that the wires go in? If you're going to post a "how to", tell how to do all of it and don't skip important steps such as the color order of the wiring.
