    You should have both a perm live and ignition on feed on a 1997 model, but they are wired the wrong way round on the Audi connector. You need to connect the yellow perm live on the HU to the red/white on the Audi ISO plug (the one above the brown earth) and the red ignition on lead on the HU to the connection marked S-Kont in the diagram below:

    If the HU is staying on with the keys out then you must have both yellow and red connected together to the perm live. Wired correctly and the HU will go off when you pull the keys out.
