Dear Greg,
If you need the cross-over for an Ethernet application, you will need the pinouts table at one of our pages: http://www.cabling-design.com/references/pinouts/10-100base_t_crossover.shtml
Then you would need a (good quality) crimping tool that runs for about $25 (absolute minimum), then you need dozen RJ 8-pin jacks for about $5 a package. You won't end up with just two connectors - at least tree should go broke in order to get used to the tool. Then you'd need a piece of stranded cable, rarely sold in short lengths, so plan for another $20-$30 expense.
Is all the above worth the efforts when you can buy a good quality factory-made cross-over cord for about $5? If you're interested, you can visit the link at the page I gave you here to order the cross-over with free US overnight delivery.
I'm not selling you a product worth $5, I'm trying to save you from the troubleshooting hassles that most likely will appear after you start to use your creation.
Sorry for the words that maybe little too rough.
Sincerely,
Dmitri Abaimov, RCDD
