Aloys,
Were these systems used on other cars in Germany? If so, are there any used ones available?
I think if I could buy a used control box (on firewall under the dash) and the matching keys, I could replace the control box and use the matching keys.
I am going to ask Hella if any cars imported to the US had these systems, but the US Hella division said they were not a US product as far as they knew. May be they just gave me the easy answer.
Thanks for the help.
Mike
