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 starting if the keys are in the
ignition. The diagrams in this section illustrate how to accomplish 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 start system will shut down. If this inter-
face 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 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
DEI 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.
