Connect this wire to the provided toggle (override) switch as shown in figure A. Connect the other wire from the
toggle switch to the PARK/NEUTRAL switch in the vehicle. This wire will test with ground with the gear selector
either in PARK or NEUTRAL. This will prevent the vehicle from accidentally being started while in a drive gear.
This input MUST rest at ground in order for the remote start system to operate. Connected properly the vehicle
will only start while in PARK or NEUTRAL.
In some vehicles, the PARK/NEUTRAL position switch activates a factory starter lock out that will not allow the
starter to operate in a drive gear. In these vehicles, connect this wire to the toggle switch as shown in figure B.
Connect the other wire from the toggle switch to chassis ground.
IMPORTANT!
Always perform the Safety Check section of this installation guide to verify that the
vehicle cannot be started in ANY drive gear and that the override switch is functioning properly.

neutral safety switch interface
Some vehicles do not have an electrical neutral safety switch. Instead, a mechanical neutral safety switch that
physically interrupts the starter wire is used when the vehicle is in any drive gear. If the remote start is inter-
faced before this switch, it will provide protection from starting in gear. However, some vehicles combine the
column shift mechanism and the mechanical neutral safety switch into one mechanical part. In these vehicles, it
is impossible to interface the remote start system before the neutral safety switch. With this type of vehicle, if
the car is left in a drive gear and the remote start system is activated, the vehicle will move and may cause
damage to persons or property.
