Hey,

Does anybody have the wiring diagram for a 1991 Mercedes 190E?  I'm doing an alarm install on it myself. Yes, I'm that crazy! For some reason I can't get the power door locks to work with the alarm. I'm wiring it with two relays exactly the way the diagram shows for a Mercedes vacuum type system.
