directly from a wire in the vehicle. The Black/Yellow wire connects to the vehicle's tach
wire, which is found in the engine compartment, although in many 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.
Learning the Tach Wire Sensing must be performed after all wiring connections are
made, and the Comfort Start unit has been programmed for Tach Wire Sensing operation
(the unit must be programmed- see pages 11-13). To perform the learning:
1- Turn the key on and off, then step the brake pedal 5 times.
2- Within 5 seconds, start the engine with key. The unit will chirp the horn once, if
connected, to indicate tach learning mode.
3- The Status Light will light to indicate that the tach signal is learned.
4- The unit will exit tach learning mode automatically 7 seconds later, or by stepping on
the brake pedal, upon which the unit will chirp the horn once and the Status Light will
go out.
20-Gauge Green/Red Wire:
Connection If Needed.
The Green/Red wire allows the Comfort Start to be
used with diesel engines, operates only if programmed (feature #3)and is also polarity-
programmable. Connect the Green/Red wire to the wire in the vehicle which powers the
glow plugs, or the wire which illuminates the "Wait To Start" light on the instrument panel.
When connected, the unit will not engage the starter if the Green/Red wire has +12 Volts;
in other words, using this wire simply delays the unit's engagement of the starter. If the

Installation Instructions
IMPORTANT!
After reading this manual, start the installation by affixing the
WARNING DECAL to a visible area in the engine compartment!
Installation Considerations: This entire booklet should be read before starting the
installation. An understanding of which control module wires are to be used and their
functions is essential. Installations will vary from car to car, as some control module wires
are required, while others are optional. Before starting the installation, it should be deter-
mined which control module wires will be used. Most installers will list these wires, then
"map out" the installation by locating and noting the target wires in the vehicle. This will
also determine the best location for the Comfort Start control module, which is mounted
upon completion of the installation.
The Comfort Start remote starting unit duplicates the actions that occur within the
ignition switch when you use your key to start the engine. Because of this, most of the
main wiring harness connections will be made at the ignition switch harness. The ignition
switch wires usually are high amperage circuits, which means that high reliability con-
nections must be made- soldering of all connections is recommended.
Caution! Avoid the Airbag circuit! Especially avoid any harness or wires encased in
Yellow or Red tubing or sleeves. Do not use a standard test light, as it can deploy an
airbag or damage on-board computers and sensors.
