Firstly like to thank radioham for all his help.

I'm trying to get 12V and aux into the center console so I can power up any device there and also route audio into the sound system. My current application is trying to power and play mp3 from my phone via the center console.

I've spent all day today trying to get a wire from the rear fuse box to the center console to power the cigar lighter attachment that radioham kindly let me have. While I was at that I decided to extend my glovebox aux wire to the center console too, I decided to parallel up the aux. So now I have an aux in the glovebox thats connected via the resistors/capacitors and the one in the armrest will bypass them. All this is to power my new phone cradle that I'm building for the HTC TyTn. None of the BMW phone cradles I've tested give me +5V with >1A, so I can't do what I did with my P910i earlier.

Well all the hard work is now complete and the WDS DVDs that I had were completely useless because my car was nothing like in the diagrams. I think I know where to plug in the 12V at the back now, atleast I think its supposed to go into pin 3 on the X11011 connector. I'll give more details when I'm finished in case anyone is interested on planning to do something similar.

I've now got all the cabling done but its not connected yet. I've got to buy a wire connector that goes into the plug at the rear fuse box. I've also got to buy a plug that goes into the audio sockets in the rear of the center console.

I have a few questions.
1. When I removed the glovebox the main wiring loom was connected to 3 things, the glovebox lighting, the glovebox torch socket and a third thing. What is this third thing and where is it supposed to sit. When I opened the glovebox it was simply hanging loose. Either I did that or BMW when they fitted my Aux. This thing look like it has a sensor or a bulb or something. It infact glows a faint red light when on. I just don't know where its supposed to click in because it has some attaching mechanism.


2. Where are the rear cigar sockets lights connected to. I don't want to connect them directly to the 12v because it will be on all the time and also won't dim with the other interior lights.

3. Anyone know the part number for the plug that goes behind the AV In Out socket in the center console at the back? Is it X13325 (6909000.9) ? But what is the BMW part no.


4. Does anyone know the part number for the plug that my 12v wire needs to be connected to so that I can plug it into the fuse box. I think its 61.13.8.364.566 but just want to be sure. I'm connecting it to pin 3 in the plug shown in the first picture. Ignore the second picture its just there to show you what part I'm actually after.

radioham

ok then i use pin 2 for the trunk sockets you use pin 3 for the rear seat sockets just checking contact for wire .i will post later

radioham

ok bruce,the contact no.is 61 13 8 364 832 also will fit is
61 13 8 364 836
they are same size
.5 1.0mm
nos 8 or 9 on roem

bump...

Anyone about that part I'm holding in my hand, what is it, where does it go?

dlevi67

It looks like a fiber optic cable / connector... I recall there is something like that for the iPod MOST connection?

bruce_miranda

You could be right but then why is it not plugged to something. But then fiber optic for what? I have a CD changer so its not like its there in case I installed one. Does anyone understand the wiring loom enough to tell me what this is? Rudy?

bruce_miranda

On second thoughts its not an optical sensor because it has like a bulb type plug that can be pulled out from the socket. Also as I mentioned it glows a very faint red light.

I think I spotted this on the WDS diagrams but still don't know where it goes or what is it. Someboy please help this is driving me nuts now.

dlevi67

I did NOT say an optical sensor. Fiber optic has nothing to do with sensors. It's a cable like any others, except that it uses photons instead of electrons to move signals around.

The MOST bus uses fibre optic to send signals (audio, nav, video) around . I reckon - though I cannot be sure - that you are looking at X13836 which is a spare optical cable connector in the MOST ring. It makes sense that there is a faint red glow, as you are seeing signals on the bus being sent by other components.

bruce_miranda

So where does it attach? Mine is simply hanging loose at the moment.

dlevi67

As far as I can tell, it hangs loose. Possibly it's used to test MOST bus functionality when servicing, as it seems to be depicted loose in WDS location pictures (like the one you pasted above) and it's diagrammed as two connectors simply connected to the bus with a temporary (testing?) loop, nothing else.
