H5/7 Violet wire – Positive Door Switch Sensing Input (Zone 3)–
This wire is the positive trigger input wire for positive door pin switch. This wire is connection for "positive"
type factory door pins(typical FORD MOTOR). Locate the "common wire" for all door pins and make the
connection of the VIOLET Wire here.
H5/8 White / Blue wire – (-) Instant Start & Turn Off Input –(See Start Feature I - 7 Programming)
This wires activates and turns off the remote starter each time it sees a momentary ground signal.
Normally only used for testing during installation or when activating the module from an after-market
system.
H5/9 White / Red wire – Tachometer Signal Connection –
Note: You should connect this wire if you program the Start Feature
II – 2
to “Tachometer checking type”,
otherwise not to connect this wire and tap the end.
Note: No connection of this wire is required, if you use the voltage or timer checking type mode.
This input provides the remote start system with information about the engine’s revolutions per minute
(RPM). It can be connected to the negative side of the coil in vehicle with conventional coils. In multi-coil
and high energy ignition system locating a proper signal may be more difficult. Once connected,
To test for a tachometer wire, a multi-meter capable of test AC voltage must be used. The tachometer wire
will show between 1V and 6V AC at idle, and will increase as engine RPM increases. In multi-coil ignition
system, the system can learn individual coil wire. Individual coil wires in a multi-coil ignition system will
register lower amounts of AC voltage. Also, if necessary, the system can use a fuel injector control wire for
engine speed sensing. Common locations for a tachometer wire are the ignition coil itself, the back of the
gauges, engine computers, and automatic transmission computers.
IMPORTANT! Do not test tachometer wires with a test light or logic probe. The vehicle will be damaged.
How to find a tachometer wire with your multi-meter
1. Set the ACV or AC voltage (12V or 20V is fine.)
2. Attach the (-) probe of the meter to chassis ground.
3. Start and run the vehicle.
4. Probe the wire you suspect of being the tachometer wire with the red probe of the meter.
5. If this is the correct wire the meter will read between 1V and 6V.
H7. 4 PIN ORANGE CONNECTOR FOR 2 STAGE SHOCK SENSOR (ZONE 1 / 4)
1 . Green Wire / Zone 1 Warn Away Input
2. Blue Wire / Zone 4 Ground Trigger
3. Black Wire / Negative
4. Red Wire / +12Volts
H8: 10-PIN MINI WHITE OUTPUT WIRE CONNECTOR:
H8/1 Yellow wire – (-) 200ma Ignition 3 Output –
This wire provides a 200mA (-) ground output that becomes active 4 seconds before the remote start unit
initialize, and remains grounded while running.
Ignition 3 output:
Some newer vehicles use a third ignition wire
which is required to start and keep the vehicle’s
engine running. If this is the case, wire an IGN 3
relay (not supplied) as shown below:
Do not connect any vehicle circuits together, they
are isolated for a resaon.

Transponder interfacing using relay:
If the vehicle has transponder system installed, you will need to by-pass the system while the vehicle is
operating under the control of the Remote Start Unit. To do this:
1.You will need a transponder key that's already programmed to the vehicle.
2.Remove the trim around the ignition switch.
3.Wrap a thin (28 - 30awg) wire tightly around ignition switch 6 to 8 times and secure it.
4.About 6"down line make another loop of approximately 2"diameter.
5.Place the key inside this loop and secure it to the loop.
6. Connect on end of the (28 - 30awg) wire to pin (87) of the relay module.
7. Connect the other end of the loop wire to Pin (30) of relay module.
8. Connect the pin (86) of the relay module to the ignition wire from the ignition switch.
9. connect the pin (85) of the relay module to the
H8/1 yellow wire of 10-pin mini white connector.
