I have the crimp tool for this connector and I know what the configuration is. My problem is a proper way to get all 8 wires in the connector for crimping.

Thanks for the help.

Well, unfortunately, not all R45 connectors are alike. I like the EZ-RJ-45, but they require a special crimp tool. AMP requires a special crimp tool.

Some have sleaves, some do not. Some have spacers, some do not.

Strip the jacket off, so it is squished by the crimp.
Basic idea is to maintain the twists as close as possible.
Insert in the correct order.
Crimp.

The EZ RJ45 allows you to insert all of them, cut at an angle if you wish. The crimp tool cuts the wires flush to the end of the connector because the wires exit the plug.

Another thing to be VERY CAREFUL about is whether the plug is rated for stranded, solid or both. Single puncture clips are rated for stranded only. Tri-clips can usually do both.

Practice, practice, practice. Find someone who has done it before and get them to show you how they do it.

I prefer to untwist at least 2-3 cm of wire and arrange them. Then use a pair of scissors to clip the end straight (about 1 to 1-1/2 cm) and then push them in to the connector right away.

As KISS stated, it depends on the connector brands and spec. There are different connectors for CAT6 than for CAT5 as well.

Never leave more than 1-1/2 cm untwisted at ANY connector including what is inside the connector.

I like to strip outer insulation about an inch back, only untwitst as far as needed, lay all wire incorrect order and perfectly flat, hold up to connector to be sure insulation is under crimp part, cut straight across with scissors and while still in your hand slide into connector, wiggle a little(not you, the wires) and crimp.
Personal thing with the EZ RJ 45, although unlikely, if the end of the cord touches metal, it can short across the wires at the end.

There are times you want a custom length.

Man this brings back memories of my Cisco classes, where I spent 4 hours one day just practicing this... over and over and over and over again!

The biggest thing I've learned is after you've got the correct supplies (as stated by KISS and CH) make sure your cut is straight and equal across all wires and makes sure you secure them into the RJ45 connector all the way to the tip, if not then it won't secure the connection and you won't know why its not working (assuming you don't have a Fluke Tester)

Then you know it's not properly RJ45 but 8P8C.

Both designations are technically incorrect. There is no Registered Jack (RJ) designations for Ethernet. Technically, it's TIA568A or TIA568B:

http://en.wikipedia.org/wiki/TIA/EIA-568-B

Perhaps the widest known and most discussed feature of TIA/EIA-568-B.1-2001 is the definition of pin/pair assignments for eight-conductor 100-ohm balanced twisted-pair cabling, such as Category 3, Category 5 and Category 6 unshielded twisted-pair (UTP) cables. These assignments are named T568A and T568B and they define the pinout, or order of connections, for wires in 8P8C (often incorrectly referred to as RJ45) eight-pin modular connector plugs and sockets. Although these definitions consume only one of the 468 pages in the standards documents, a disproportionate amount of attention is paid to them. This is because cables that are terminated with differing standards on each end will not function normally.
