Q-tion about the phone mute feature...

[RussZTT]

I have the 2001 330ci. On the steering wheel I have the phone features but I do not have a phone in the car nor want one. I am wanting to hook something up to the mute button. I read somewhere about how to get to the wiring harness in the center console but how do I know which wire is for the mute button? Is this correct? I don't want to take the steering wheel apart just to find the wire for the mute button. Any input???
Thanks!!
