    Bose wiring for GAMMA BOSE coming from V8 or URS4

    Hi there.

    I have a 200 20V but have the BOse hardware except fro the radio.
    Here is the thing. When I bought the car, it had a GAMMA CC ( no Bose) but somehow hooked up to Bose speakers, although I think they all went.
    So, first, I sent all 4 BOSE spekers to BOSE USA and had them rebuilt, so pretty sure they are like new ( they sure look like it).

    So, a little later I thought that there was something fishy about that GAMMA CC head unit, so I got myself a Gamma BOSE ( US spec, coming from an Audi V8), which, by its part number, it is the same as the BOSE units found on URs4 cars.
    It is the GAMMA BOSE made by plaupunkt.

    Anyway, so we went deep in the radio and found that there is some re-wiring but most , there are 2 pairs of green/black-green cables that are just plain cut.
    We don´t know where they go. It seems to have the CD changer control, so the midddle conector shoudl be "blank" as there is no CD changer. IS that right?
    In that case, where are the cables to the speakers plugged?

    The connector with the speakers seem to be there as there is some sound......

    Here is the cables I am talking you about. ( Here below).....

    Any ideas on the set up? I also have the display in the IP for stations which is working with current Gamma

    Here is also the exact connector pattern of my radio.....

    Any idea where those cables should go?

    Should all be there (link below) in the Omnibus radio wiring spreadsheet (note: multiple tabs/sheets) created by Steve Mills (RIP) on quattroworld.

      Hey URS4.
      Thanks a million ( as always). Stupid question but, how should I read the numbers vs the pinout diagram itself? I am thinking about turning the diagram upside down and starting:
      1 3 5 7 9
      2 4 6 8 10

      Same for the other connectors?

      So, based on that, I should completely forget about those 4 cables.....I don´t see them in this pinout diagram. Could those be from something else?

      I´ll try to follow this, but since the original Radio on the car was a DELTA BOSE, don´t know if the wiring would still be compatible.

      Anyhow, thanks a lot for the info.

      Will keep you posted

      Cheers

        For the T10 connector for example, it looks like the diagram translates into

        10 8 6 4 2
        9 7 5 3 1

        and so on.

          Hey URS4.
          Thanks a million.
          Like posted on the "other" post, I finally got all my wiring done, so OK for that.

          Now I have another problem following this one, which is the Gamma Bose radio I got.
          It will just show up "safe" when turning it on.....

          I´ll open a new thread on that...
