If the starter engages and the vehicle is a General Motors product or Dodge Dakota pickup, refer
to the following 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 Technical Support for an alternative shut-down method. Do not return the
vehicle to the customer until this feature is properly installed!
Every vehicle built this way requires that the shifter be placed in park to remove the keys from
the ignition. As a result, it is possible to use the key-in-ignition sense switch to prevent remote
engine starting if the keys are in the ignition. The diagrams in this section illustrate how to accom-
plish this.
Diagram A, applies to all General Motors vehicles at the time of publication of this guide. Diagram
B 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
engine starting system will shut down. If this interface is used it is important to inform the
customer to close the driver’s door before inserting the key into the ignition when the remote
engine starting system is active. This will allow the customer to turn the key on and shut the
remote engine starting system 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 engine starting system from activating if the key is left in the
"run" position. If your remote engine starting 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
Technical Support if you need assistance in making this interface.
IMPORTANT!
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.
