I'm in the process of adding a remote alarm system with a door actuator and I want to incorporate it with the existing triggers of the factory alarm. First order of business is locating the factory alarm module. I read posts stating it's underneath the passenger footrest. What I find there is a warning sticker about an airbag/seatbelt tesioner...and that it should be unpluged...etc. The car is a 1984 300SD. Would the factory alarm module be located elsewhere on models with airbags? Any help would be great!
