    Perm live is the fat red wire with white stripe on the black ISO connector (top right as you look at the HU from the back), shown below as UB+:
    Don't see how this is gonna help you as without the perm live the HU won't work and will lose all its presets. I'm guessing you need to swap over the perm live and the ignition on live (as Audi wire them back to front) so it'll remember your settings?
    The ignition on live is the yellow wire with red stripe, 2 across from the brown earth shown below as S-Kont.
