Correct, the alarm module is under the passenger footrest. It watches all the doors including hood and trunk. The tilt-sensor (anti-towing) was under the rear seat, left side. It was removed after the 1987 model year because it caused too many false alarms. The convenience relay was installed in its place. My '87 300D had the alarm removed and an aftermarket one installed; the wiring was all messed up, took me a year or two to get things reasonably back together. My '95 E300 has the factory alarm in primo condition, my first experience with one that works as installed.

Some other cars do have a lock/unlock switch on the dash: W210 E-class, W140 S-class, etc. The switch is available from M-B and looks like a window switch but with a key symbol added. I plan to add one to my car.

Another thing I want to do is to add a central-locking defeat switch so that I can unlock the driver's door while leaving all of the other doors locked as a security measure. All it takes is a switch to turn off power to the central locking pump.
