H3/3 GRAY (-) hood pinswitch input
This wire MUST be connected to hood pinswitch. This input will disable or shut down the remote start when the
hood is opened.
H3/4 BROWN (+) brake switch input
This wire MUST be connected to the vehicle's brake light wire. This is the wire that shows (+) 12V when the brake
pedal is depressed. The remote start will be disabled or shut down any time the brake pedal is depressed.
H3/5 VIOLET/WHITE tachometer input
This input provides the module with information about the engine's revolutions per minute (RPMs). It can be con-
nected 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 Finding the Wires You Need 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 with 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.
