Phone connection?

[JonD]

Thanks for that
So, correct me if I'm wrong
RED-Green is 12V Always
Green is 12V Switched
Yellow&Blk is Phone Mute (whatever that means)
Brown is Negative/Ground

I'm just planning to use The Green 12V Switched with a hard wire kit for a dashCam and that's it basically.. so the cam switches on with the ignition.
And the ground wire of the kit to the Brown
Will that work guys?
Thank You
