PIN 5: GREEN: (-) START ACTIVATION TRIGGER
This wire allows a host alarm (-) Negative Auxiliary Channel Output to activate a Remote Start or it can be
connected to a Negative wire of a factory keyless entry system. If the Factory Keyless Entry System wire can
produce a Negative output for 1 second or 3 short pulses within 5 seconds, that system could also be used to trigger
a remote start. See diagram below for Factory Keyless interface.
PIN 6: GRAY: - HOOD SWITCH
Connect this wire to a switch that is at ground when the hood is open. If an existing switch is not available, then one
must be installed. When this wire is grounded, the remote start is inhibited. This is a mandatory connection!
PIN 7: PURPLE: + BRAKE RESET
Connect PURPLE wire to the side of brake pedal switch that shows +12 volts ONLY when pedal is depressed. This
will turn off the remote start if someone attempts to drive the car without the keys or if the Ignition key is not turned
on all the way. Brake pedal must be pressed for at least 1 second before reset will occur.
PIN 8: RED/WHITE: (+/-) TACHOMETER/VACUUM SENSE
This wire MUST BE CONNECTED to the vehicle to sense the engine running. This is so the control module can
control the starter motor to determine when to disengage the starter and to prevent the starter from engaging when
the engine is running.
This system has three methods of sensing an engine running condition:
•
True Tach Learning:
This is the best and most reliable method.
•
Semi-Tachless/Timed Starting:
An alternative for vehicles with hard to locate tach sources.
•
Vacuum Sensing:
When all else fails.
