6. Start the vehicle using the 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 and check your VIOLET wire H1/1 starter output
connection. The heavy gauge VIOLET wire must be connected to the
ignition switch side of the neutral safety 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 removed from the ignition
cylinder. This configuration prevents mechanical operation while the vehicle
is in gear but offers no consideration for the electrical operation. Because
of this potential problem, your 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 wire. 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 but is also is the easiest
to install, providing the vehicle you are working on has this ECM input.
The installation required for this application (shown below), is a 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.
