Customer message:

“Hello Elyza,I’ve got a -95 W124 and would like to connect my Star diagnosis SD Connect4 to it. But I do not know how to connect the wires from the SDconnect c4 mux?

The Black plug is of course ground, which will go in pos 1 on the Data Link
The White plug is marked KL15 which I understand is going to pos 16..?
The red plug is marked 12V B+, don’t know where this goes.
The blue plug is marked K-Line/LIN, don’t know where this goes.
There is to groups of plugs with two plugs in each. One Green and one yellow. One group is marked CAN HS and one is marked CAN LS. The green plug in each group is marked CAN_L and the yellow is marked CAN_H. ”

Engineers Solution:
Here is the solution I found on a forum. I have tried it successfully as follows:
Connect Red to +12v battery directly, White to pin 16, Black to pin 1, and Yellow to pin 8 (some motors like M111 series) to get HFM error and live data, Pin 7 for HVAC, Pin 6 for airbag etc.

The Result:
After trial and error a gazillion times, this is what we ended up with, and the software actually responds!!

So it seems the BLUE jack, marked K-Line, is the one you’ll have to move from pin to pin according to the software’s instructions. Mission accomplished

If you also happened this problem , please can try this way to sort out, hope it also help you 🙂
