I am sure the origional poster found the answer to most of the questions by now, but has not been reported here.

Black is ground
Orange is 12 volt power at all times
Yellow is 12 volt power switched at ignition

What is the purple? Does anyone know. Local dealer wasn't interested in figuring it out through service manual.

I am hoping for audo mute for mobile phone, but want to confirm it before I hook it up.

If that is not what it is, does anybody have a cheap solution to get audio mute for phone?

Thanks.
