remote start harness (H3) wire connection guide

H3/1 BLUE/WHITE status/defogger output
This wire supplies a 200mA output as soon as the module begins the remote start process. The H3/1 BLUE wire
can also be used to activate the defogger trigger (latched/pulsed) 10-seconds after the remote start engages.
(See the Feature Descriptions section in this guide for details about programming this output.)
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 pressed. The remote start will be disabled or shut down any time the brake pedal is pressed.
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 igni-
tion 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 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.
