Here's an old trick that helps. Cut about an inch of cable and remove the
copper, keeping the insulation. When you go to align the wires, use the
pieces of insulation to help keep the wires in the proper position. After
you crimp the connectors, trim the short pieces of insulation. Sometimes
you can just pull it out. You might want to recrimp if you pull it out.

Mark,
Some cables have the pairs molded together, so they almost look like there
is only one wire, when in fact there is a pair. I'm not aware of any cat5e
cables that only have 4 wires.
That being said, you can make a 100BaseTX or 10BaseT ethernet cable with
only 4 wires and 2 RJ-45 connectors, but it's difficult to get the wires in
the right slots. Hold the RJ-45 with the clip towards the floor, and the
pins away from you.
Then, insert the wires in the 1st, 2nd, 3rd, and 6th position, and crimp.
Make note of which color goes into which position, and do the same on the
other end for a straight through cable.
Here's a page that seems to have decent pinout descriptions for 4 pairs:

Just pretend they have only 2 pairs, green and orange, on their pictures,
and that's what you need to do.
As I said, it can be difficult to get the wires in the right pins, since
you're missing wires, but I have done it before.
