WIRING CONNECTIONS
H5/7 VIOLET Wire (Positive Door Input) (Zone 3)
The VIOLET wire is the positive trigger input for +12volt positive style
door circuits. The VIOLET wire will attach to the wire in the vehicle that
provides +12volt positive when the door is opened. The same wire in
the vehicle will provide 0 voltage or negative ground when the doors are
closed. This type of door circuit is most common with Ford vehicles.
H5/8 WHITE/BLACK Wire (Instant Start and Stop Input)
The WHITE/BLACK wire will activate and deactivate the remote starter
when it sees a momentary (-) negative ground.
This wire is used for testing purposes and to activate the remote starter
from another source.
H5/9 VIOLET / WHITE Wire (Tach. Input or Oil Sensor Connection)
(Tach Input Connection)
Note : No connection of this wire is required, if you are using the voltage
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. To test for a tachometer wire, a multi-meter capable of testing AC
voltage must be used. The tach wire will show between 1V and 6V AC
at idle, and will increase as the engine RPM increases. In multi-coil ignition
systems, the control module can learn individual coil wires.
IMPORTANT! Do not test for tach wires with a test light or logic probe.
How to find a tach 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 tach wire with the red probe
of the meter.
5. If this is the correct wire the meter will read between 1V and 6V.
IMPORTANT NOTE: You must program the “Tach Signal” before
trying to remote start.
Oil Sensor Signal Connection
Locate the wire connected to the oil sensor on the dashboard or to the
generator in the engine compartment.
