Hi All I'm undertaking my cruise control retrofit on Saturday as everything has arrived but have a couple of questions with regards to removing the airbag and wheel. ELSA says in big red writing to keep the key in the ignition while disconnecting the battery whereas other guides and forums say to have the key nowhere near the ignition...also do I need to undo the airbag screws while the battery is connected or will the steering lock not engage as long as key is in the ignition when I disconnect the battery. With regards to taking the wheel itself off, again the forums and Kufatec guide I found give mixed messages - some suggest the wheel needs marking while others suggest the wheel is keyed so doesn't need marking at all. I have the 4-spoke multifunction wheel currently if that makes any difference. Any help much appreciated!
