Tach Wire
Orange/Black Wire - (Tach-Sensing Wire):
The Orange/Black wire is
an engine speed or tachometer sensing wire. The system actually uses two different methods
of monitoring the engine's starting/running status during the remote starting process- the
Orange/Black tach wire, and voltage sensing. The tach wire is typically more accurate in
monitoring the engine status, and its use is recommended. There is no programming
involved, or need to configure the unit for one method or the other, as the system will
automatically use either the tach wire input, or voltage sensing.
CONNECTION:
Connect the Orange/Black wire to the vehicle's tach wire, which is
typically 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 the reading will
increase with engine speed.

4-Wire Connector
Pair of Blue/White Wires - (Sensor #1 Input/Output):
Pair of Green/White Wires - (Sensor #2 Input/Output):
These two sets of wires will open during remote starting operation, but otherwise re-
main closed. When adding the RS-6 to host car alarm system, these circuits may be used
