Testing Your Installation; Mechanical Neutral Safety Switch Considerations - Marksman M7a Installation Manual

Testing Your Installation

Caution! The follow procedure must be performed after the installation of the Remote Start Device. It is the
responsibility of the installing technician to complete these tests. Failure to test the unit in the following manner
may result in personal injury, property damage, or both.
1. Test the brake shutdown circuit: With the vehicle in "Park" (P), start the vehicle using the remote
transmitter, Once the engine is running, press the brake pedal. The vehicle should shut down immediately.
If the vehicle continues to run, check the brake circuit "White/Violet" wire.
2. Test the "Hood Pin" shutdown circuit: Start the vehicle using the remote transmitter, Once the engine is
running, pull the hood release and raise the hood. The vehicle should shut down immediately. If the vehicle
continues to run, check the hood pin "White/Black" wire connection.
3. Neutral Start Safety Test:
A. Set the vehicle parking brake.
B. Block the drive wheels to prevent vehicle movement.
C. Sitting in the vehicle, turn the ignition switch "On" or "Run" position. But do not start the engine.
D. Step on the brake pedal and shift the gear selector into "Drive" (D).
E. Put you 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.
F. 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 (6-Pin White, Starter Output) 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 if 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), 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 is 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 from the black 7-pin mini connector 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 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.
