Got everything connected except for the 12v to junction box.

Hello! Does anyone know how to connect A34 * 5B (23-pin connector integrated with the power distribution box, front). Will it be the same as in the Junction box in the E87 series (pin 3,5,6,7,21,22,23) to 12V ?

[Cowboy]

I was looking for an answer to my question for a long time and found a description of the 23 pin plug (X4010) for the E90 series.
Although the Junction Box in sei F is a bit different, I connected the same pins (pins 3 and 22 to 12V) and everything works as it should.

Hello. Has anyone managed to get this test platform working? Is the above diagram correct? I'd also like to build a similar setup.

Using the diagrams from posts 1 and 4, you can set up a test bench for CAS4.

To display KOMBI, you need a HU.

You will need: Start/Stop button with steering column key reader, OBD, JBE, ZGM, CAS.

Thanks for your interest. I want a kit just to add a new key. I only have Cas4, coil, ZGW, and a start button. Will that be enough to activate the new key on the bench?

I disconnected JBE from the test bench and everything works.

You can do it without using JBE.

[jansmerfowski]

Ok, thanks a lot. I have a question. I don't fully understand post #4. If I have a JBE, which pin is (+) and which is GND?
