The resistors are 3.9ohm or there abouts to stop the airbag light being on.
The buttons do work and it has been done as has the airbag from an R56 which requires wires to be cut and joined using an r56 loom. Also with the correct wires from an r53 you can cut and solder on the button cables.
Your friend is bmw WDS which can be found on google to follow the wires
