Worst cast scenario you just need to modify the cable & stuck a switch on it to toggle pin 8 on/off as needed.

The ones with pin 8 active are just older versions of the cable. The one with it disabled is ideal for e90 newer than 03/07 & that era, these leads often come with a black adapter to re-enable the pin 8 (by just tying it to pin 9) so it will also be suitable for e46/e39/e63 etc. With these K+DCAN cables there are two subtle different versions, one with pin 8 enabled, one with it disabled. Here, I will chip in with a few words of the reason why you should have Pin 7 and Pin 8 on your K+Dcan cable and how to use the switch modeĬonnection by soldering is a bad option as it limits the usefulness of the interface, I have an adapter but consider a switch to be a better option
