Blue: (+) or (-) FACTORY HORN INPUT
This optional input can be wired to the factory horn honk output of the vehicle. When the system is in the
"locked" state and this wire receives an input (programmable for (-) or (+) for a minimum of 0.5 seconds, the
system will send a trigger message to the 2-way remote(s) only. This is useful on vehicles that have a factory
security system.
Note: If the factory alarm is triggered while the system is in the "locked" state the only indication will be
from a 2-way remote (if equipped) when receiving a signal. There will be no trigger confirmations when
unlocking the system with the aftermarket remote. The system can receive a (-) or (+) input from the vehicle
and is programmable through Horn Input Polarity Jumper (see below).

Polarity Jumper
White/Blue: (-) REMOTE START ACTIVATION INPUT
This input wire is used to manually activate/deactivate the remote start sequence by pulsing it to ground
(programmable for single or double pulse activation/deactivation). It can also be used to activate the Turbo
Mode feature of the system if attached to a ground through an optional momentary switch and the Timer
Mode feature is enabled (see Activation Pulse Count or Turbo Mode in Feature Menus for more details).
Additionally it can be used to activate Manual Transmission Ready Mode when connected to ground through
an optional momentary switch.
Violet/White: TACHOMETER INPUT
This input wire connects to a tachometer signal in the vehicle. It provides the system with information about
the engine's RPMs. This is a required connection when installing the system in a manual transmission vehicle.
Black/White: (-) PARKING BRAKE/E-BRAKE INPUT
This input wire connects to the parking brake/e-brake wire in the vehicle. This wire must have a ground and
the Remote Start ShutOFF Switch must be plugged in and turned ON for the remote start to operate. This is a
required connection when installing the system in a manual transmission vehicle.
Green/Black: (-) FACTORY ALARM DISARM OUTPUT
This 200mA output is used to disarm the factory alarm and triggers when remote start is activated, when the
system is disarmed and when activating the trunk release output. It typically connects to the Factory Alarm
Disarm wire in the vehicle. This output can be programmed to activates with unlock, trunk release and for a
single or double pulse output (see OEM Alarm Disarm options in Feature Menus for more details).
Green: (-) DOOR TRIGGER INPUT (N/O OR N/C)
This input wire comes factory set for use in vehicles with (-) door trigger circuit. This wire is used to monitor
the door trigger(s) when entering manual transmission mode. This wire (or the Violet (+) Door Trigger input)
is a required connection when installing the system in a manual transmission vehicle. This wire can also be
programmed for a N/O (Normally Open) or N/C (Normally Closed) circuit.
