Hi, just purchased my first BMW and have been looking into retrofitting cruise control and the OBC but seem to find an answer to my question, i was wondering if i could just purchase the new stalk for the OBC and fit that and then buy the multifunction slipring and the multifunction buttons and fit them and then have them both coded at the same time rather than buy the wiring loom and alter the wiring as shown in the online guides, any help would be much appreciated.
