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 a fuel injector or 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.) 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.)
