follow the instructions that came with the 451m, The car has vaccum doorlocks and you also have to programm you alarm for 3.5 second door lock pulses.
 Vacuum Type Door Locks |
Found mostly on Mercedes Benz vehicles, the movement of the door lock actuators is controlled by a central vacuum pump. The switch changes polarity on a single wire that may rest at power or ground depending on the state of the door locks. You can duplicate this with at least a 2 second pulse. If the alarm or keyless entry you are installing does not have a 2 second or longer duration option for the door lock outputs, do not use this diagram (it will not work unless you incorporate a timer into this circuit).  |

Is up to the installer to test all wires with a DMM whenever possible.
