H3/5 VIOLET/WHITE Tachometer Input
This input provides the module with information about the engine's revolutions per minute
(RPMs). It can be connected to the negative side of the coil in vehicles with conventional coils. In
multi-coil and high energy ignition systems locating a proper signal may be more difficult. (See
Installation Points to Remember section of this guide for finding the tachometer wire.) Once
connected, you must teach the system the tach signal. (See Tach Learning section of this guide.)
H3/6 BLACK/WHITE Neutral Safety Switch Input
Connect this wire to the toggle (override) switch as shown in Figure A. Connect the other wire from
the toggle switch to the park/neutral switch in the vehicle. This wire will test ground with the gear
selector either in PARK or NEUTRAL. This will prevent the vehicle from accidentally being started
while in a drive gear. This input MUST rest at ground in order for the remote start system to
operate. Connected properly the vehicle will only start while in PARK or NEUTRAL.
In some vehicles, the park/neutral position switch activates a factory starter lock out that will not
allow the starter to operate in a drive gear. In these vehicles, connect this wire to the toggle switch
as shown in Figure B. Connect the other wire from the toggle switch to chassis ground.

IMPORTANT! Always perform the Vehicle Safety Check section of this guide to verify
that the vehicle cannot be started in ANY drive gear and that the override switch is
functioning properly.
IMPORTANT! DO NOT use T-Taps or scotch locks for this connection.
