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.

I have only used my K+DCAN interface with DCAN cars.
Q : Is there anything else to do for switching from K-Line to DCAN then disconnecting pin 7&8? Unfortunately I don’t have a DCAN model available.Ī : As soon as you connect the interface to the car and your computer, run DCAN.exe to configure the comms rate. Q : So you have to physically connect (K-Line) or disconnect (DCAN) pin 7&8?Ī : Yes, I think connection 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.
