For starters, as I already told you, the PV-1 does not use an RJ11. That is too big. It's an RJ9.
If you hold the plug, with the wire facing downwards and the clip side of the plug away from you, so that you are looking at the flat side of the plug the colours are as follows from right to left; Black Red Green Yellow.
Black: Right - minus
Red: Right + plus
Green: Left - minus
Yellow: Left + plus
In addition the seller who is in the other post of mine, in the picture will sell you a ready made phone cable which is entirely correct, any length you want, wired up correctly, in black if you want black. So you see, I try to assist you before. For some reason, you ignored my advice and still talk about RJ11, which is incorrect. Fact; RJ9 Best of luck.
