Please post back if you have any more problems or questions.

You want to refer to the article that the others posted and use the T568B color scheme, repeat after me:
orange/white-orange-green/white-blue-blue/white-green-brown/white-brown

Now say that 100 times!

One thing the article wasn't specifically clear about -- it implied but it's important enough to mention again -- is once crimped, there should be less than a half-inch of any pair untwisted per spec, and don't untwist the pairs from each other; this should keep crosstalk down within spec.

Of course I'm talking Cat5e spec; if you're wiring for gigabit then you should be buying manufactured certified patch cables or using a cable company that has the meters for cert'ing to Cat 6/6a
