Thanks! I've been brainstorming for quite some time and I haven't been able to find anyone who put the mute button on the steering wheel, mostly because the wires carry some kind of coded signals and not a straight electrical current. But I saw that other clock spring in the forum I mentioned and said, hmmm, that looks like a possibility.
I'm just missing a lot of information. I bought a clock spring and I'm going to open it up and see what we're dealing with.
