[HELP] What Wires are this in my E82 Trunk

p][m · 12-17-2018, 08:40 AM

Hi guys,

I just found in my E82 trunk I have a TCU module and also all this cables, that I would believe those are the cables to connect the MULF 2 HIGH module.

I have search a lot for this, but all what I find are DIY for who doesn't have this cables in the trunk.

According to my E82 VIN this is what I have:
S612A BMW Assist
S633A Preparation, mobile phone, Business
S663A Radio BMW Professional
S8SCA Telematics access request,country-spec.

So I have Bluetooth but I don't have the USB, which is my aim.

Since I have all this cables in my trunk, this means that I only need to buy a MULF2 HIGH + Plus cable from MULF2 to USB + USB plug + Codding?

I see the Fiber plug, but don't know where are the fiber ends to plug there.

Also I have this purple plug coming from the hole in the top of my trunk which I have no idea what and for it is, do you know?

Thanks in advance for your help.

I can help with answering part of this is even though this is an old post.

the blue plug, one fiber optic black plug go the mulf2. my car has that but not originally the TCU which I now have so Im trying to see how these all wire up.

idk what the pink plug is for. I have it in that harness, not dangling like yours.

hope that partially answers your question
