White/Red Wire: (-) Tachometer Signal Connection
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. This wire requires programming (See Start Feature Stage 2 to
program to “Tachometer Checking Type”).
In mult-coil ignition system, the system can have individual coil wires. Individual coil wires in a mult-coil ignition
system will register lower amounts of AC voltage. 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. Electronic
components of the ignition system will be damaged.
How to find a tachometer wire with your multi-meter:
1. Set the ACV or AC voltage (12 or 20V).
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 at idle and will increase with RPM.
Note: No connection of this wire is required, if you use the voltage or timer checking type mode.
One Wire Multiplexing Door Locking Systems
Some vehicle’s (Chrysler, Mazda and Ford Probe and others) use one wire to lock and unlock the doors.
Example: When the door lock controller sees a signal thru a resistor it will unlock. If a signal is received
without a resistor the doors will lock. Some use 2 resistors. One for lock and one for unlock. We have
developed patented plug-in fuse resistors for this application. Simply remove the fuse from our door lock
module and replace with correct resistor value fuses that matches the vehicles door lock switch.
Wiring:
1. Connect both the green (lock) and the blue (unlock) wires to the vehicles one wire lock/unlock wire.
2. Connect our violet polarity input wire to +12v or to ground. To match vehicles door lock polarity.
3. The white and the brown wires will not be used.
