Help needed with socket wires!!!!!

Intasun32

In the course of decorating I have removed the first house telphone socket, spupidly without making a note of the wire to terminal connections. There is plenty of advise of the net but to make things difficult the one box I disconnected is old wiring.
There are four wires, GREEN, BROWN, BLUE, ORANGE, unlike the modern wires of 2 blue & white and 2 orange & white.
Can anyone with a good knowledge tell me which coloured wire connects to which terminal numbers.
Your help would be most appreciated. Thank you.

I'm not sure whether there are details on there about old wiring schemes though.

Thanks Heinz, that was the site that I found too. Cheers
BT want to charge £100+ to connect it but will not give any advice.

That's because, legally, only BT can touch the innards of that master socket.

If you only have one exchange line, it's likely only two of those wires are in use and the other pair are spare. You're looking for 50 volts across the pair (75 volts on ring). Do you have a DC voltmeter?

Are you talking about the main BT box?

Just found this but not had time to see if it's any good for you. ( I have to go out)

On older installations (pre-1980) cream or grey cables were used. They contained conductors coloured blue to pin 2, orange to pin 5, brown to pin 3 and green to pin 4 (if used), on some conversions green was used for pin 3 and brown for pin 4.

Thanks for all the advice.:beer:
It is the first main socket into the house, in which runs off all the extentions. From this socket, the old wiring is run to and connected to the old bakerlite BT box inside the door in which the wire from the telegraph pole outside is connected. As stated there are four wires only the blue & orange were used as the green & brown are tied up together. I have been told that I should connect them to terminal 2 & 5 in any order, does that sound correct? I wish I would have noted the connections when I removed it but I didn't notice the old wiring. I don't have a DC Voltmeter, I'm just an average to bad DIYer.

Ah. If only you'd said you knew which two were in use and which 2 weren't, you'd have been told 'terminals 2 and 5' immediately.

Thanks Heinz, a pal just told me blue 2 & Orange 3. I'm never gonna get this room finished.

So would have I.
