    The box has there connectors coming out of it:



    Then it come with this loom as well aftermarket im guessing:

    Well that box is iirc an alpine cd changer adapter to work with existing audi head unit.

    Which head unit are you wanting to fit so can check connectivity, as it may need permanent power, plus possibility of manual on/off or via ignition by tapping fusebox feed or some canbus network connectivity for the on/off signals.

    Andy may know more on this, sure he'll pop in at some point.

    It looks as though you only have 4 wires in the brown connector, which suggests to me, that you have a half amplified system. That said, it also looks as though that "other" aftermarket lead (Picture 4), is an adaptor for said system.

    So, best plan of attack would be to connect that aftermarket lead into the car, and add the stereo wiring to the end. you should then have full sound from all four corners, without it, you would only have sound from the front two speakers.

    Hope this helps.

    Yeah I'd agree with that aswell, now the princess is out of my hands lol, had time to study it more, that aftermarket adapter doesnt appear to have any canbus wires to connect through either, so again need radio model to see what the crack is on that score, but I'd follow what arrkon suggests.

    Stereo wiring mess on my02 A3 8L

    I like to think I know what I'm talking about Nigel

    I think an 02 8L would only have a K-line. Even so, iirc, the adaptor is missing a pin in that cavity anyhow just thinking about the vag com backfeed issue

    CANh and CANl would be in the middle connector of the mini ISO's (green)

    The previous owner of my car told me that he took out an Alpine system.

    So i take it i wont need the box in pic 2 and connector in pic 3?

    I want to put in a sony HU, i think its: a Sony MEX-BT3600U (just off the top of my head need to check it in my garage).

    Connectors wise: Have i got everything i need to make the HU work? What else will i need?

    Thanks.

    Correct, should only need the connector in pic 4, your Sony should plumb in on the end, should then have music, happy days.

    Worst case, if the stereo doesn't store the stations, swap the yellow and red leads over. Simples

    Thanks for all your help. Got a working stereo now after repinning.

    The stereo only comes on if the car is running. I want it to run a soon as i turn the key when i get the dash lights or i dont even mind it permanetly live even if the key is not in. How can i achieve this?

    Any ideas how i can get the stereo to work without having the engine running?

    Can it have a permanent live? If so, where's the best place to get the perm live from?

    You mean without key in at all or just ignition switched on, but no engine running, cause an ignition switched feed would be sufficient.

    You just need to connect both yellow and red leads from the Sony together then both of them connected to the permanent live on the Audi black iSO connector. This will keep the hu live so you need to turn it on/off manually. Or you can run a proper accessory feed from the fuse box, fuse radio s-kont this will keep the hu live until you pull the keys out.
