Carsoft Multiplexer Adapter Cable MB Sprinter 14pin D-Sub DB37 Pinout Breakout Box

[newbit]

Hey Fellows,

could somebody please give me the pinout for these Carsoft Adapter cables with the 14pin to D-Sub DB37 connector on it?

I've got this "complete" Carsoft Multiplexer Kit with Dongle and V12 Software. But the 14Pin Adapter cable is missing.

I can't get the adapter cable seperate from the Kit.
But I can get a similiar looking adapter cable from the breakout box.

611487

Does anybody know if these two different adapter cables are pin compatible?

I've already found some kind of schematics for the Multiplexer, but not for the adapter cables.
I could figure out, that on the MB38:
Pin 1 = GND
Pin 2 = (+) output power, circuit 15
Pin 3 = (+) output power, circuit 30 (Battery 12V)

goes to the Breakout cable DB37:
Pin 1 = GND
Pin 2 = (+) output power, circuit 30 (Battery 12V)

The rest looks like it is just connected pin by pin one to one.
This could also be the reason that there is no Pin2 on the Breakout Box
and pincount goes up to 38 but have only DB37.

The 1,2,3 pinout on the MB14 is similiar to this.

Any help would be much appreciated.

Thanks in advance
