I seem to have a harness that i need to repin, but the wiring diagrams im finding do not match my plug exactly.

For example:

This is the diagram i am using:

Pin---Description-----------Pin---Description

1----Mic(pos)--------------25----Mic(pos)
4----AUX-GND-------------10----AUX-GND
15---Crash Sig.-------------7----Crash Sig.
17---30 Power+ 5A---------2----30 Power+ 5A
18---30 Power+ 10A--------1----30 Power+ 10A
19---MIC(neg)------------12-----MIC(neg)
21---MIC Shield-----------11-----MIC Shield
23---Shield---------------22-----Shield
31---SOS sig.f Button-----18-----SOS sig.f Button
33---Wakeup-------------15-----Wakeup
36---31 GROUND(neg)-----14----31 GROUND(neg)
37---emerg. Speak.(pos)--21----emerg. Speak.(pos)
38---emerg. Speak.(neg)--20----emerg. Speak.(neg)
50---emerg. butt LED-----17----emerg. butt LED
54---GROUND-

I dont have the following pins

4
18
23
54

But I do have the following ones that arent mapped
3
46

46 I think is phone cradle which doesnt matter, no idea what 3 is.

Any one help?

this is what came out of my car and im replacing with a combox:

I found 2 pins wrong.

Apart from that every pin matches another page i found (http://www.bimmerfest.com/forums/sho...d.php?t=772784)

That matched my cabling.

But when BimmerGeeks tries to connect it says its not there, error in communicating.

What could be wrong with the install?

Plugged in all the cables bar one gsm one

Still no joy, Tools32 says error communicating with the car.

Any one got any ideas about what to check?

My wiring on the car is as follows:

1 yellow
3 blue
15 red/black
17 red / yellow
19 black
21 clear
31 light grey
33 yellow
36 brown
37 yellow / white
38 white / blue
46 green
50 blue / grey

Seems to be different to everyone elses?
