Hi. Can someone point me in the right direction? I've run cat5 all thru my new house that's being built, and I need to now connect the cable to the drops in the walls. I have no idea in what order to connect the wires. Can somebody lend me a hand please?

Thanks..
CJ

A little more help would be nice. What EXACTALLY are you trying to do. The standard is

wo o wg b wb g wb b

on both sides for a straight through cable. Email me and explain your problem and I can help.

ok if you are using a hub then you can put the ends on in what ever order you want, just as long as it is the same on the other end of the cable. if you dont have a hub then you need to folllow this pattern:
1 3
2 6
3 1
4 4
5 5
6 2
7 7
8 8

4,5,7,8 arent assigned. they dont do anything.

so hold the wires out flat and the head, always the same way. and write down the colors of the wires, i find it easiest to number the wires but keep the same numbers with the same wires through the whole thing. take and splice one head in the order 12345678 and the other one in the order 36145278 and that is called roll over cable.

hope i didnt confuse you even more

Here's some advice from someone who has had to re-do a few connections in a house. Do some research BEFORE you start crimping ends.

1) Get some good tools: Crimper, tester, sharp wire cutters.
2) Check out: http://www.duxcw.com/digest/Howto/network/cable/cable1.htm
3) The easy way to connect at the Switch end is just crimp a RJ45 on the end of the wire, and plug it in.
4) Test each wire before using it.

I'm sorry grazzhopper, but some of your advice is false. The reason Cat5 cable is in the form of 4 twisted pairs, is for noise immunity, which will be seriously compromised if you happen to use two wires from different pairs for a signal. Do the research, stick with the standard, and make them think a pro did it.
