JB4 N54 Wiring Harness
Hello dear comunity,

I recently got my hands on a JB4 for my e93 335i.
My problem now is that the harness that it came with is kinda suspicius and i can not find out what is going on. I would like to replace the usb data cable with the bluetooth connect kit but its connected to the main harness.

So i thought someone on here could defitely help to identify the problem and help me find a solution.

If you need more info like pin nr. etc let me know.
I want to remove the usb and attach the bluetooth connect kit.

Here are some pictures of the botched harness
