3. Sitting in the vehicle, turn the ignition switch to “ON” or “RUN” position. But do not start the engine.
4. Step on the brake pedal and shift the gear selector into “DRIVE” (D).
5. Put your foot over the brake pedal but do not press down on it. Be ready to step on the brake to shut down the Remote
Start Device.
6. Start the vehicle using remote transmitter.
a. If the starter does not engage, the test is complete.
b. If the starter engages, immediately step on the brake pedal to shut down the system, recheck your VIOLET wire
(H1/1 starter output wire) connection. The heavy gauge VIOLET 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.
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 selector position.
PARK/NEUTRAL ECM INPUT:
The Park/Neutral ECM input is the preferred method of installation. This not only maintains the integrity of the factory circuit,
it is also the easiest to install, providing the vehicle you are working on has this ECM input.
The installation required for this application (shown below), indicates in the slight reconfiguration of the control switch wiring.
Shown is a typical GM Park/Neutral ECM input circuit. To connect the Remote Start unit to the GM Park/Neutral ECM input:
1. Locate the Orange/Black reference wire in the “C2” connector found at the ECM in GM B Body vehicles or, locate the
equivalent reference wire in the vehicle you are installing the Remote Start Unit in.
2. Connect the BLACK/WHITE Neutral Safety Switch wire (H3/4) to this reference wire.
NOTE: If the optional remote starts enable toggle switch is installed, connect the one side the enable switch to this
reference wire and connect the other side of the enable switch to the BLACK/WHITE Neutral Safety Switch wire (H3/2) of the
Remote Start unit.
The reference diagram below shows a typical GM B Body ECM reference wire and how it is to be connected to the Remote
Start Unit.

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 allow a margin of safety and will prevent
the vehicle with a Mechanical Neutral Start Switch from starting in gear.
WE ADVISE 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 operators’ 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
