PU-3915A Pinout Needed

Unread post by xu9j4 »

Dear Friends,

Can you reveal the secret of PU-3915A CD player connector? I could not find any pinout description in the Internet. The socket is 12-pin MQS type, the same size as two plugs (for aux and changer) in quadlock fakra connector, which is quite popular in PSA audios. Unfortunately, the connections are not the same at both ends. All I know: 7 wires, GND on 3 and 10, battery+ on 9.
I would appreciate any information on the pins functions or a description of the cable that is used here.
The unit is made by Clarion and can be found in C4 Picasso II, Peugeot 2008 and 208 - as far as I know. PSA reference number 98105176ZD-01.

Thank you in advance,

Greg

Hi again,

The question is answered by... me, based upon some older schematics and own tests. Here it is:

1 CAN HI
3 GND
5 L
6 R
7 CAN LO
9 +12
10 AUDIO GND

The cable SMEG-to-CD: 1-3 2-7 3-9 4-6 7-1 8-10 10-5

I think the connections are the same as in 9642598480 cable (for Blaupunkt IDC-A04 CD changer). Its description is not to be found by the simple Internet resources searching, either.

Good luck,

Greg
