911 (964) Turbo - Blaupunkt CD wiring

[en6jwrs]

Hi All,

I hope I have posted this in the correct section and hope someone can help - I think this is going to be a real challenge.

Car is a 964 Turbo which has a factory fitted Blaupunkt head unit with CD Changer. The CD Changer is model no CDC-1 with Part Number 964.645.111.00.

The cable which attaches the headunit to the (power supply) of the CDC changer has come adrift. Unfortunately the 8 wires have detached from the (DIN?) connector which (obviously) has 8 pins and will now require resoldering.

I believe I have identified what the 8 wires are:
Red - 14v constant
Yellow - 14v switched
Black - Gnd
Green - Audio L
Blue - Audio R
Green / Blue - Audio Gnd
Orange - Bus 1
White - Bus 2

However, I have no idea how to match these to the correct (numbered) 8 pins on the connector.

Is anyone able to assist, or point me in the right direction?

Many thanks in advance, if any further information is required I will do my best to provide it.

get a diagram of a harness online or worse yet buy one from halfords and then return it

This any use to you?

Thanks both.

Porsche want to charge me £420 for a new cable (it is a Porsche, maybe also VW specific part, so not available at Halfords etc)

The link was very interesting and came close to solving the issue, I just need the colour to pin number relationship for a 8 pin DIN?

Any other ideas, thanks for reading, I realise this is a very specific issue!

im sure its not a proprietary system. is it not similar to anything here:

RC, thanks again. I have trawled Google images but without joy.

The plug itself is not propriety, but I think the cable is. It is a standard DIN 8 pin layout like this:



I have 8 wires (which I believe) are defined as such (from a table on a wiring diagram which MAY relate to this unit):

1 = bus 1 (txd)
2 = bus 2 (rxd)
3 = 14v dauer (German for constant)
4 = 14v schalt (German for switched)
5 = gnd
6 = gnd audio
7 = audio l
8 = audio r

However linking the colours of the wires to function and then confirming that the numbers above match the layout of the DIN plug is not easy.

The only clue I have is I think the audio gnd was actually linked to pin 2 on the DIN (not pin 6 as suggested above).

Thanks again for reading and helping!

Did you solve your problem - I have exactly the same issue! The cable from the head unit to the remote CD magazine in my 911 964 turbo has come apart and I don’t like the idea of paying ~£500 for a replacement Porsche cable. Any advice gratefully received

Judging by the age of the OP's post he's had nearly 14yrs to solve it, or move it on. Any decent auto electrician should be able to resolve this as I fail to see how it can be a Porsche product, albeit now likely obsolete and Blaupunkt DAB+Bluetooth retro head units take over the space
