2007 bmw 328xi coupe need amp

ok so here is the problem I have run into, got a friend who has a 2007 bmw 328xi coupe amplified system 6 speaker and 2 underseat subs, the info I pulled for wiring in the output converter did not match the plug or wiring from the factory amp. It is fed with what looks like a digital optical cable and there was no remote wire in the plug for turning the amp on. There was a large black plug with about 24 pins in it. The twisted pairs were there but there were 2 lots of the same colour codes for the yellow set and the blue set for the rear speakers. pics are posted;

the amp plug pictured above does not match any of the bmw amp pics I have been able to find. I also found this creature which I am sure feeds the subs as well pictured below;

So what I need is 1) what wires do I wire in the loc and 2) will the regular scoshe loc work for this application.

this was 1 source I used; http://www.bavariansoundwerks.com/product-extras/d110.e46s_Subwoofer_System_Install_Guide.pdf

Bloody good luck there. You're holding the speaker leads in your hand in the photo, I'm guessing 4 satellites, 2 tweeters yellow/red and yellow/brown, blue/red and blue/brown are the fronts and blue / YELLOW and blue/brown and blue/white and blue/brown the rears) test whilst BLACK/ white and BLACK/ brown are probably the subs. This unit uses CAN data switching, no pulse lead available. The other box form those purple Fakra plugs looks like an antenna coupler, i.e.Nav. AM/FM Sirius etc.

Be very careful, the BLACK/ white and BLACK/ brown COULD be the CAN leads.

Looked at the down load, your first problem is that it shows the previous model, E46. Yours I believe (07) is an E90. Secondly having looked at some pages in the down load I wouldn't trust something that makes me use blue butt connectors which are the wrong size any way. Get your hands on a Mitchell guide for the right wiring, incidentally over here, we have about 3 different h/unit specs. on that car.

yeah I solder/shrink all the connections I make and I was aware that it was the previous model I just can not seem to get my hands on the correct wiring. I want to hook the output converter into the sub leads that way he can use those to adjust the sub I am adding. I am going to use a bussman bp/hhh fusetap to add the key on remote signal.

found my answer check this out if you need the answers on the bmw hookup for the loc. http://www.e90post.com/forums/showthread.php?t=64582&highlight=ultimate+subwoofer+guide
