    Bose wiring diagram

    I have a 2005 Boxster S with PCM 2.1 and Bose Surround Sound. The previous owner had cut out and removed the bassbox from the rear deck. I have acquired a bassbox but I don't have the matching plug from the Bose wiring harness. Does anyone have a wiring diagram or can provide a picture of the plug from the harness side?

    Here is a pic of the Bose harness.

    Thanks for your help.

    Re: Bose wiring diagram

    I am getting there. I found this diagram on this site that explains the pin out wiring from the amp. I now know what are the wires leading to the bassbox.

    Now I need to find out how they map to the bassbox

    Can someone take a picture and post it of the male 12-pin plug (harness side)? Thanks.

    WOW! I can't believe someone would cut wiring on a Porsche like that! Hopefully the rest of the vehicle was treated much better.

    Re: Bose wiring diagram

    Well, working with a friend who is smart on stereos, I was able to get my bassbox reconnected. I ended up making a custom connector using a 9-pin connector for computer hardware plus a couple of spade connectors for the power wires. I had to take the box apart to trace all the wires to verify how it all wires together. We also used a simple test speaker to verify the + and - speaker feeds.

    In the end it worked pretty good, other than once when I accidently touched the two power leads and blew a fuse. The custom 9-pin connector is a little fragile and care will be needed when disconnecting the bassbox.

    For future reference, here is the pin out arrangement for the Bose subwoofer wiring harness:

    1 - Amp power +
    2 - Amp power -
    3 - Subwoofer remote
    4 - Subwoofer +
    5 - Subwoofer -
    8 - Rear Right -
    9 - Rear Right +
    10 - Rear Left +
    11 - Rear Right -
