GM vehicles that have the neutral safety switch built into the column shifter can usually be identified by a
purple starter wire. Typically, vehicles that use an outboard mechanical switch use a yellow wire from the
ignition switch to the mechanical switch and a purple wire from the mechanical switch to the starter itself.
Remember, this is only a rule of thumb and is not intended as a substitute for proper testing.
We suggest the following procedure to test for vehicles manufactured in this way.
NOTE: You must complete the remote start system installation before doing the following test. Ensure that
the remote start system is functioning normally. This includes connecting to the brake as a shut-down.
testing the neutral safety switch
1. Make sure there is adequate clearance to the front and rear of the vehicle because it may move
slightly.
2. Make sure the hood is closed and there are no remote start shut-downs active.
3. Set the emergency brake.
4. Turn the key to the "run" position, this will release the shifter.
5. Place the car in drive (D).
6. Place your foot directly over the brake pedal, but do not depress it. Be ready to step on the brake if
the starter engages.
7. Activate the remote start system.
8. If the starter engages, immediately depress the brake to shut the remote start system down. If the starter
does not engage, no additional safety system is required.
If the starter engages and the vehicle is a General Motors product or Dodge Dakota pickup, refer to the fol-
lowing 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 properly installed!
Every vehicle built in this fashion 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 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 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
