Hi, I'm new to this forum. I found an older thread on the soft top and roll bar control modules for a 500 sl, and I have a similar question. I am trying to figure out how the roll bar control module works on a '91 300 sl. I was hoping someone might be able to post a wiring diagram and/or a list detailing what the inputs and outputs at each pin on the module are. As I understand it, this module takes input from switches located on the rear suspension and contains angle sensors and accelerometers internally and deploys the roll bar when the required sensor outputs are produced. What other inputs does the roll bar module receive and what other modules does it interact with? I believe it also locks the seat belt retractors when the angle sensor produces a certain output, is this correct? If so, how does it lock the retractors and does it lock them directly or through another control module?

Thanks. I would really appreciate any input/advice you could offer.
