If the starter engages and the vehicle is a General Motors product or Dodge Dakota pickup, refer to the follow-
ing text and diagrams for an alternative shut-down method which will prevent the starter from engaging. If the
vehicle is not a General Motors product or a Dodge Dakota pickup, please call Directed Electronics Technical
Support for an alternative shut-down method. Do not return the vehicle to the customer until this feature is prop-
erly installed!
Every vehicle built in this fashion requires that the shifter be placed in park to remove the keys from the igni-
tion. As a result, it is possible to use the key-in-ignition sense switch to prevent remote starting if the keys are
in the ignition. The following diagrams illustrate how to accomplish this. The first diagram applies to all General
Motors vehicles at the present time. The second diagram applies to all pre-1996 Dodge Dakota pickup trucks with
2.5 liter motors. This solution has one side effect - if the customer inserts the key in the ignition with the driver's
door open, the remote start system will shut down. If this interface is used it is important to inform the cus-
tomer to close the driver’s door before inserting the key into the ignition when the remote start is active. This
will allow the customer to turn the key on and shut the remote start down by pressing the brake without the key
sense wire shutting down the unit prematurely.
In addition, you must connect a tan (+) shut-down input to the yellow wire on the relay satellite ribbon cable.
This prevents the remote start system from activating if the key is left in the "run" position. If your remote start
system only has one tan input, you must use diodes to isolate the ignition circuit from the brake switch input.
However, due to future manufacturer changes in vehicles, it is possible that this may not apply to all vehicles.
In addition, color variations are possible from model to model; make sure to test the circuit carefully. Please call
Directed Electronics Technical Support if you need assistance in making this interface.

NTT!! Once the interface is complete, attempt to remote start the vehicle with the door
closed and the key in the ignition. The vehicle should not start. If it does, recheck the connections.
