P2-6: Dark Green: NEGATIVE OUT WHEN RUNNING
This (-) output is powered up 1 second before ignition, remains on during run time and remains on 1 second after
ignition is shut off. It can be used to temporarily disable a factory security system or an anti-theft device during
runtime.
P2-7: Orange: ANTI-THEFT OUTPUT
Output (-) used to control a relay that neutralizes a vehicle circuit to prevent starting, or a flashing LED to indicate
anti-theft status.
See Stage 1 - Level 4 of the programming chart for the available options and the user guide for the explanation of
those options.
P2-8: Light Green: HORN OUTPUT
Output (-) used to activate the factory horn circuit (low current) or an external relay for high current or for positive
circuit.
This output can be connected to the vehicle's factory horn to give an added audible verification or confirmation and is
also triggered by the AstroStart alarm when in violation. See programming options related to the this output at Stage
1 – Level 10 on page 20 and Stage 2 – Level 3 on page 23.
P2-9: Red/White: +12V OUTPUT
Output used to feed external accessories relays. This output is protected by a 1A auto-reset fuse
(PTC).
Note: Do Not Use for 2
ND IGNITION or 2ND STARTER applications.
P2-10: Black/Green: TACHOMETER INPUT
Input used to detect whether or not engine is running.
GAS-POWERED VEHICLES:
Connect Black/Green wire to the signal (RPM) wire of the Ignition circuit. This wire can normally be found at
the negative terminal of ignition coil, on ignition module or at the back of the instrument cluster.
Note: For additional protection, it is recommended that a 0.5A fuse be added at the junction to ignition coil.
DIESEL-POWERED VEHICLES:
Most of the newer diesel engines now have a signal wire that can be read as a tachometer (Rpm) wire. If the
vehicle you’re working on does not, you may have to add a DTS-2 module (part no. 310-066-502). This
module converts electromagnetic fields generated by the alternator into a tachometer signal. Wiring
instructions are supplied with kit.
AstroStart has collected useful information on vehicle circuitry (wire colors) on a CD-ROM called AstroChart.
See your distributor for more details.
HYBRID-POWERED VEHICLES
Most vehicles with hybrid engine cannot provide regular tachometer signal due to the simple fact that the
tachometer signal source (the gas engine) only engages when the battery needs to be charged. If an
installation is required on that kind of vehicle, ground the “Tachometer Input - Black/Green” and program
the Level 2 as “Hybrid Engine” mode. That programming will give you a 5 seconds start output allowing
the remote starter to be installed without monitoring the tachometer signal.
P2-11: Black: GROUND INPUT
Input that provides a reference ground for the module.
You must always be sure to have a good ground point. This connection is the one that creates the
majority of problems. A bad ground connection is difficult to diagnose because, most of the time, the
problem will be intermittent.
ALWAYS ENSURE BLACK WIRE IS CONNECTED TO THE LEFT KICK PANEL OR THE FIREWALL.
