My 84 190E has an aftermarket alarm system installed. It is a 'disabler' type where the car wont start/operate without plugging in this 'cap' which has a mysterious combo of pins in order to complete the circuits involved in the alarm: fuel pump, spark, etc..

I need additional 'caps' but I dont know who makes this system. On the cap it says DE WE KO. I did a net search and have come up with nothing.

Is anyone familiar with this alarm? Who makes it? Where can I get the schematic?
