I have a RJ45 Modular Telephone Wallplate and I wish to wire the cat5e cable to it from the switch. Except i have no idea which wire goes where.
I've put a photo of what it looks like here: http://users.bigpond.net.a
Thanks in advance!

ccomley, I'm not sure what you're talking about - I see 8 pins.
Donhayes has given you a 568B pinout. This is correct if it matches the cable on the other end. However, an alternative pinout, used in homes (sometimes) is the 568A pinout, which to confuse you ;) I will list (pin one is on the left, pin eight on the right - as you look at it like you're about to plug something in, with the tab down)
1-white & green
2-green
3-white &orange
4-blue
5-blue & white
6-orange
7-white & brown
8-brown
I list the 568A pinout, because that really looks like a Telecom plate - and may have a diagram somewhere for an A pinout, and not a B. If so, to make it work with the other end, simply swap the oranges and greens.
However, it's not the best practice to have one end directly into a device, and the other end into a wall plate - that's 1/2 structured, and kind of strange. I'd recommend trying to find a jack for the other end as well - or at least an inline coupler - then this gives you a little flexibility and ability to troubleshoot in the future.

pseudocyper, It is listed as a RJ45 Telephone wall plate and and the the other end (from network switch) is in 568A. Referring to the image posted what would you recommend wiring which colors to pins (A-H)
pinA---- pinB----
pinC---- pinD----
SOCKET
pinE---- pinF----
pinG---- pinH----
By the labelling on the plate, though unclear which label corresponds to which pins, the following labels are shown:
pinA -> "L+"
pinB -> "L-"
pinC -> "AUX"
pinD -> "EARTH"
pinE -> "T3"
pinF -> "R3"
pinG -> "T4"
pinH -> "R4"
Not sure if this any help. But appreciate the feedback so far.
Not sure if this is going to be "up to spec" for Cat5 or whatever, but thinking PinA corresponds to Pin 1:
A - green with white
B - green
C - orange with white
D - Blue
E - Blue with white
F - Orange
G - Brown with white
H - Brown
Try to keep the twists of the pairs as close as you can to the termination. If it's a phone plate, I would think it probably has screws which you twist the copper around - try to minimize how much insulation you have to strip at the end to go around the screw.
If you're doing this for the halibut, or you're really cheap, OK. But I would have to second ccomley's suggestion to get another plate - one certified for Cat5 or better. You will get better performance. With the one you've got there, the type of termination, and the quality job you do may effect your transfer rates - if it's got physical connectivity problems these will show up as Ethernet errors causing higher layer retransmits - which you will perceive as "being slow".
I would also recommend another plate. Although this is an RJ-45 connector I suspect it is not designed for network use. The layout of the pins appears to be such that you would have to 'peel' back the jacket and un-twist the wires more than is acceptable by the TIA568A/B standard. This causes cross-talk between the wire pairs and can reduce or destroy network performance. Perhaps it is an old network jack or more likely, with the ability to punch down multiple wires, for use with special phone systems requiring 3 or 4 pairs.
How does everyone seem to know the pinout here? I spent 3 years punching down CAT5, 5E & 6 and never saw one RJ-45 connector that the punch-down connections went in series with the actual pins . You need a wiring diagram or color code for any jack and I don't see one in the photo. Also the visible labels Aux, Earth, T3 & R3 would indicate it is a special application jack not configured for standard network use, possibly USOC wiring. If you want to trace the actual pin to the punch-down position all of the above configurations will work starting with the pin on the left and moving to the right, not "starting at PIN1 (top left):" Some comments start with orange/white and some green/white both are acceptable so long as the other end is wired the same. One is TIA568B standard and the other TIA568A. The former is more common in the US, not so in many other countries. Just thought I would throw in another 2 cents worth.

That's bizarre, I've seen all manner of faceplates and I've never seen one like that before. It seems to have each of the eight connectors four times over! And none of them are labelled up.
All the plates I've used before have just eight connectors, one for each pin, and they are all clearly labelled with colour coded paint though you still have to check you're using the same convention as the far end i.e. is that orange-with-white or white-with-orange.
IF you can work out which connector relates to which of the 8 pins in teh RJ45, then this page will give you the full detail on which colour cable should be punched into each. :-)

If you can't, I suggest you buy another faceplate which has only 8 connectors, and colour-codes or numbers them. Or get out your multi-meter and use the continuity testing setting to work out which pin on the RJ socket connects to which punch connector on the back.
