If you're using the type of faceplate with the wires spread out spaghetti-wise among a three-quarter circle of eight terminals built into the faceplate, I believe the wiring's the same as the plugs: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown. If the order gets reversed, it's no problem as long as they match at both ends. If you have a multimeter, you can try doing a continuity test to see which pin matches up to which terminal.
If you're using modular keystone jacks (jacks which snap into the faceplate), the wiring standards are 568A/568B; you can find out about these specs (and quite a few others) at <A HREF="http://www.cablingdirectory.com/" target="_new">http://www.cablingdirectory.com/</A>. Typically the punch down points will be labelled with the appropriate colors; if not, twisted pairs are typically intended to punch down at adjacent points. You can switch any pair with any other pair, as long as the ends match up.
I should mention that keystone jacks are much easier to work with, much more scalable, and tend to stay within IEEE specs better than the spaghetti-wise wiring.
