Re: Colour coded for a reason....
Worked out that if you covered one of the pins in the new-fangled BT modular jacks with sticky tape, then when the phone rang, and was answered, it not only didn't answer, but kept on ringing!M
I used to do something like that - but with the phase pin of various extension leads or power leads.
The leads always seemed to work perfectly for me, but for the boss it'd never work. Carefully trim it right and the tape becomes quite invisible unless you look close enough.
