how to change bt phone plug
need to fit one of these onto a cable.
have not removed the old one but would it be safe to assume the coloured wires are standard? else I would need to hack away at the plastic plug to
see how the wires are connected - and hopefully discover they are not one colour!!

Can you not see the wires to glimpse the colours? Certainly on that photo you can see the wires, from an angle it may be possible to check the colour
order. Pretty certain they're standard though... If in doubt plug it in at work

They are not wired all the same all devices are different and It depends on what is fitted on the original lead and what the device is. If it is a 2
wire device a modem or a modern foreign phone its usually 2 wire, does it have a RJ11 plug on the end, clear plastic, 4 contacts or 2 centre contacts,
if so the 2 centre wires go to the 2 outer contacts on the BT plug.
Really you need a crimper but you can get a kit from Maplins which comes with a die and a couple of plugs which you squeeze on with a pair of pliers,
the easiest alternative if the original has an RJ11 plug is to buy a RJ11 to BT adaptor alternatively for a couple of quid postage I can make you up a
lead and mail it out.

it is a six position plug,
only pins 2 and 5 are required for most telephones,
pin 3 may be wired for a ring signal

I believe the outer sheath is "D" section so provided you get the "D" the same as originally it should be correct.
At one company I worked for we used to fit these for BT and I believe they are insulation displacement so you will need to get a tool from Maplins.

most of the bt sockets have internal connections (for extensions) you may be able to use those and remove the plug altogether.

What are you doing exactly just replacing a plug putting a new plug on an existing cable or cutting off an rj11 and converting it to a BT plug.

Have a look at this web page, about half way down.

you'll also need an RJ11 crimp like this...
