It's realy not that bad. A common cable tracer (nickname - tone and probe,
fox and hound, diddle stick) can be bought for $80-$100 US and will find
the right wire in about 60 seconds. There's a sender you plug into the jack
on the 'known' end and an inductive pickup you slide around the patch panel
until you hear the distinctive signal.

Here's the one I have : http://www.tselectronic.com/greenlee_prog/701k.html

(no idea about the company, I just googled it)

I wouldn't work in a comms cupboard without one.
