MKDR33, im pretty sure there is about three threads on removing a steering wheel. I just couldnt find any on the installation of one. From what i have read, the airbag would only go off if it had power, not by impact alone. So if you disconnect the power, it will be fine. Im not sure about the theory on draining the power, as i didnt think that it was actually stored anywhere? Most people that removed their airbag wheel usually only complain about the airbag light that stays on. So, if you are going to remove it, be prepared to fix this by the methods in those threads. As mentioned in this one, my air bag light still operates as normal, which could be due to a resistor.
Mick, any pics or help you could offer would be great for me or anyone else that may need this thread. Im pretty sure to reset the computer, it was to turn the ignition on and then hit the drivers door strike button several times. But ylwgtr2 could confirm this, as i remember reading it from another thread that he posted on. The only wiring diagrams that i have are the ones that have been made available on these forums. So if you require a specific one, have a search around, save them, then print it out if you want a hard copy.
