2) Tach Sense:
If the vehicle is generally hard to start (example: requiring the starter to be engaged
for more than 1 second) this method will produce more consistent remote starting.
With this method the Orange/Black wire reads the engine speed (tach) informa-
tion from a wire in the vehicle. The Orange/Black wire connects to the vehicle’s
tach wire, which is found in the engine compartment, although in some cases it
may also be located inside the vehicle. To use a multimeter to verify the correct
tach wire, set it for AC Volts scale. The correct wire will read 1 to 6 volts AC with
the engine idling, and will increase with engine speed. An additional adjustment
control and LED indicator allows tuning the unit’s tach wire sensitivity.
1) Position the selector switch for Tach Sense (left position).
