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 this 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.

MECHANICALNEUTRALSAFETYSWITCHCONSIDERATIONS:
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
selector position.
KEYINSENSORCIRCUITS:
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 allow a margin of safety and will
prevent the vehicle with a Mechanical Neutral Start Switch from starting in gear.
AUDIOVOX ADVISES THAT YOU MAINTAIN THE FACTORY CIRCUIT WHENEVER POSSIBLE. The following two
circuits may be used only if the above circuit is not available.
Note: When completing an installation using either of the following key in sensor circuits, if the operator inserts the
ignition key while the vehicle is running under the control of the Remote Start, the vehicle will shut down. This
must be explained to the operator as it is in contrast to the normal operation of a vehicle utilizing an electrical
neutral start switch and is inconsistent with the operator's manual.
Additional information concerning Key In Sensor methods 1 & 2 are listed below and should be reviewed before
considering either alternative.
Method 1 will allow the safety required for the remote start unit and prevent the vehicle from starting while in any gear
other than Park or Neutral while the key is in the ignition cylinder. However, if the key is left in the ignition switch and
the door is left opened, the added relay will be energized causing a 150mA drain on the battery.
Method 2 will allow the safety required for the remote start unit and prevent the vehicle from starting while in any gear
other than Park or Neutral while the key is in the ignition cylinder. However, the original factory key in chime module
will not alert the owner that the key has been left in the ignition switch. In addition, this may also effect other warning
tones such as the light on reminder.
These situations should be carefully considered before altering the vehicle's wiring and must be fully explained to the
consumer.
The following circuits may be used only if the above circuit is not available.
METHOD1
To connect to the key in sensor as shown in method 1:
A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.
