gets +12volts. If the brake lights switch in the vehicle switches +12 volts
to the brake light circuit, connect this wire to the output side of the
brake switch. This will allow the remote start to shut down if an attempt
is made to operate the vehicle without the key while running under the
control of the remote start. In most vehicles, in order to shift gear, the
brake pedal must be depressed. The brake input will in turn cause the
remote start unit to shut off. See below diagram.

WHITE/BLACK WIRE –
NEGATIVE SAFETY SHUT DOWN INPUT —
The WHITE/BLACK wire provides an instant shutdown for the remote
start, whenever it is grounded. Connect the wire to the hood pin switch
previously installed. This wire must be routed though a grommet in the
firewall and connected to the hood pin switch.
Important! This connection is a safety wire and must be connected
as shown and tested as specified. Failure to do so may result in
personal injury or property damage. See detail of wiring in the
following diagram. This wire may also be used if the vehicle brake light
circuit switches ground to the brake lights. An isolation diode must be
used for ground switched brake light circuits and must be connected to
the output of the brake switch.
WHITE/RED WIRE—Tachometer Signal connection—
This input provides the remote start system with information about the
engine’s revolutions per minute (RPM). It can be connected to the
negative side of the coil in a vehicle with conventional coils. In multi-coil
and high energy ignition system locating a proper signal may be more
difficult. Once connected, you must Program the Start Feature D – 2 to
“Tachometer checking type” and teach the system the RPM signal.
(See Start Feature D – 2 Programming.)
To test for a tachometer wire, a multi-meter capable of testing AC
voltage must be used. The tachometer wire will show between 1V and
6V AC at idle, and will increase as engine RPM increases. In a
