H3/2 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 Finding the Wires You Need section of this guide.)
Once connected, you must teach the system the tach signal. (See the Internal Programming Jumpers section of
this guide.)
H3/3 BROWN (+) brake switch input, zone 1
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. This
wire will also trigger the security system if the brake pedal is pressed while the system is armed and will report
Zone 1.
H3/4 GRAY (-) hood pinswitch input, zone 1
This wire MUST be connected to hood pinswitch. This input will disable or shut down the remote start when the hood
is opened. It will also trigger the security system if the hood is opened while the system is armed and report Zone 1.
H3/5 BLUE/WHITE (-) status 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.)
