I've laid quite a lot of Cat5e throughout the house and I'm now ready to put ends on. Some ends are going into boxes and others into plugs (I don't know the correct terminology).
I'm just not quite sure on how to do it, a friend has loaned me some tools from his work but he doesn't actually do the manual work so wasn't exactly sure how to do it, here's what tools I've got:



I also need to know the order the wires go into the plugs and the back plates, I've also got some back boxes but the numbers and colours the wires go into are different to another one I had, they are both Cat5e so I'm wondering why they are different, the one on the left are the ones I'm using:



Any help would be mucho appreciated :)
 
The back plates are different because there are two Cat5e wiring standards (A and B), the second (one on the right) is only showing B, typically we use B here.

So your backplate would follow the wiring of:

1 - White Orange
2 - Orange
3 - White Green
6 - Green
4 - Blue
5 - White Blue
7 - White Brown
8 - Brown

Taking 568B as your plug standard, the RJ45 plug on the cable would be wired (from left to right, pins facing upward):

1 - white orange
2 - orange
3 - white green
4 - blue
5 - white blue
6 - green
7 - white brown
8 - brown

Fairly simple, wire the plugs according to "B" standard and do the wall jacks the same.

You're interested in the 2nd pinout.

As for the two types of jack you have the one on the left shows both standards, follow the punch down for the "B" column and the one on the right just punch them down as labelled.
 
Use the layout for the one on the right for your sockets, the extra options for the left one are if you are crossing the cables...

For the RJ45's - plastic bits that go on the end you plug into your PC so not the sockets..


Turn the plug so that you can see the copper bits at the top facing you
Pin 1 is far left hand side

Pin 1 white orange
Pin 2 Orange white
Pin 3 white green
Pin 4 blue white
Pin 5 white blue
Pin 6 Green White
Pin 7 White Brown
Pin 8 Brown White

Plenty of diagrams on the web..

You want the patch cable layout, NOT the crossover. That should do you for the cabling. Not sure about the plugs there but as long as the same color cable goes to the same pin on each you shuld be ok (you'll need to use the punchdown tool for this, the one in the middle of the top pic)

Hope this helps :)
