Hey everyone,

I have been pulling my hair out trying to find a wiring diagram that tells me where to find an ignition switched power connection. I have removed the Bose Symphony II head unit from my 05 S4 convertible and want to use the Bose amp and speakers (for now), the Metra harness I got does not have a remote power wire and I probed all the factory wires with no avail.
Does anyone know the color code and location of a switched power wire I can pick up.
I searched this and many other forums, even bought the subscription to the Bently eBahn thing.

I know its been done...Can anyone help??
