Andy: If you have the wire 'Push fit' type of socket there should
be a colour code by each connector. I got a batch of sockets from the
local maplin shop, which had such a colour coding - also if you have
a BT style 'push fit' tool - this can be adapted, by sanding away the
leading flat side to be used with such sockets. Works quite well, did
ten cable runs - all worked straight off. (I have yet to flood wire -
just did my office).

Also if you are able to make custom cables - and have a multimeter -
you can make a poor mans CAT5 cable tester using two plugs, 4 1K ohm
resistors and two bits of cable. i.e. for one plug wire pin 1 to pin
2 via a 1K ohm resistor, same routine for 3-4, 5-6, 7-8 . Then on the
other plug break out the leads to a handy 8 way connector block or a
bit of strip board - then plug the 'dongle' bit at one end of the
cable, the break out at the other - with the multimeter you should be
able to comfirm the presence of 1K resistance between the pairs of
pins (if its open circuit you have a break, if there is 0 resistance
you have a short), then do pin 1 to pin 3,5 and 7 in turn - all
should register open circuit. Then do 3 to 5, and 5 to 7, then 3 to 7.

Of course double check that you have the right plugs in the right
sockets, as by using the multimeter you are injecting a slight
current into the wires.
