How to wire up a bt telephone line cord?

The damaged line cord on my BT Relate 2100 has a RJ11 on one end and (I think) a BT431A plug on the other end. It is a 3 core cord (Yellow / Red / Black) and I need to know if I can get a new cord that is the same 3 core. I bought one from ebay and then found it was only 2 core and it didn't work. 

 

I have a repair kit that will attach a BT431A plug to my old cord but I don't know which of the colour wires attaches where on the 431A plug end.

 

Thanks for any help......
