To test the integrity of the Neutral Start Safety Circuit:

1)  Set the vehicle parking brake.

2)  Block the drive wheels to prevent vehicle movement.

3)  Temporarily disconnect the Brown/Black positive shut down wire from the vehicle's brake switch.

4)  Sitting in the vehicle, start the engine using the vehicle's ignition key.

5)  Step on the brake pedal and shift the gear selector into reverse.

6)  Allow the transmission to shift.  When you feel the engine pull, do not move the gear selector just turn 

the ignition switch off.  DO NOT attempt to remove the key.

7)  Keeping the brake pedal depressed, activate the RF transmitter in an attempt to start the vehicle.  

  The car should not start.

8)  Repeat the above test this time move the gear selector to the drive position. 

If the unit attempts to start, failing this test, recheck your Yellow Wire's connection. This wire must be 

connected to the ignition switch side of the Neutral Start Switch.  If the vehicle you are working on 

does not have an Electrical Neutral Safety Switch, it will be necessary to reconfigure the Remote Starts 

Wiring to accommodate the vehicle. The information concerning the Mechanical Neutral Safety Switch 

provided below will help you to determine if the vehicle you are working on has this type of safety 

switch and will provide alternate wiring methods to accommodate this situation.

CAUTION!  REMEMBER TO RECONNECT THE BROWN/BLACK NEUTRAL SAFETY WIRE 

TEMPORARILY DISCONNECTED IN STEP 3

 MECHANICAL NEUTRAL SAFETY SWITCH CONSIDERATIONS:

Mechanical neutral safety switch configurations differ slightly in that they do not offer the same level of 

safety  when installing a remote start device.   Often when the ignition switch is turned off while the gear 

selector is in any position other than park or neutral, the mechanical function will not allow the key to be 

turned to the start position or be removed from the ignition cylinder. This configuration prevents mechanical 

operation while the vehicle is in gear but offers no consideration for electrical operation.  Because of this 

potential problem, this installation requires the additional connection of a safety wire from the remote start 

device to the vehicle Park/Neutral ECM Input or the vehicle  key in sensor.  This connection will prevent 

remote start operation if the key is left in the ignition switch regardless of the gear selectors position. 

DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE OPERATION 

OF THE MECHANICAL NEUTRAL SAFETY START FEATURE.

 KEY IN SENSOR CIRCUITS:

If the vehicle you are working on does not have or you cannot locate the ECM reference wire, there are 

two alternatives available.  Although not preferred, the vehicle Key In Sensor may be reconfigured to al

-

low a margin of safety and will prevent the vehicle with a Mechanical Neutral Start Switch from starting 

in gear.  

THE MANUFACTURER ADVISES THAT YOU MAINTAIN THE FACTORY CIRCUIT WHENEVER POS-

SIBLE.  The following two circuits may be used only if the above circuit is not available.
