RI am trying to connect an OBD2 unit to a friend's R1200RT but the service plug on his bike has different pin placements than on my F800GS.
Does anyone know which of the 4 pins are which on the R1200 service plug? His plug is under the right side triangular cover and his model is 2015.
I found the +12V and earth pins with my multimeter but the other two pins have weird voltages on them. One should be +12 when the ignition is turned on, but it doesn't.
Any help appreciated, especially a photo.
