Does anyone know specifically what I need to do for my 1982 380SL? There is no electric vacuum pump in this one as far as I know.

I have been to 3 installers, who all say they can do it, but start talking about the electric pump. I would prefer to do the job myself than let the cowboys loose, but need to know specifically what bits I need to buy, and what problems to overcome.

An alarm installer for my previous car (500SE) was unsuccessful in getting the remote unlocking to work after assuring me he knew how to do it. He spent hours on the locking alone, and finished up by saying that the electric actuator was too quick for the other vacuum operated locks to react. So only the driver's door unlocked. The solution offerred was to convert the central locking to electric, which I rejected. The 500SE with electric pump seems an easier solution than a 107.

Ideas please so I can get an alarm fitted.
