Congratulations on your purchase of the RS-3 Remote Car Starter. The RS-3
will allow you to start your vehicle's engine from the comfort of your home or
office,allowingyourvehicletowarmupin winter and cool down in summer. When
you leave your vehicle, simply set the climate controls for what you desire to be
operating upon remote start - heater, defroster or air conditioning.
The RS-3 is an "Add-On" unit designed to be used in conjunction with another
remote control unit such as a remote vehicle security or keyless entry system.
Wehighlyrecommendthatthissystembeprofessionally installed, as the com-
plexityofthemodernautomobileandthenatureofcircuitstobeaccessedisoften
beyond the abilities of most do-it-yourselfers.
There are several safety considerations with using and installing the RS-3Re-
mote Car Starter. Among them are:
-This unit is for Automatic Transmission vehicles only. Installation in a manual
transmission equipped vehicle can result in property damage or personal in-
jury.
-This unit is for fuel injected gasoline engines only.
-Children should not be left unattended in, or be allowed to play with the activat
ing transmitters of a remote starter equipped vehicle.
-Do not use this unit in an enclosed structure or garage.

!! WARNINGS !!
Do not attempt to install this Remote Car Starter into a manual transmission
vehicle! Doing so could cause serious property damage, personal injury,
and will void all warranties!
Be aware of, and avoid, any airbag circuitry! Due to the fact that an installer
will not be in a normal, upright seated position, severe injury may occur in
an accidental airbag deployment!
The use of a Digital Multimeter (DMM) or Volt-Ohm Meter (VOM) instead of a
standard testlight is recommended. This can greatly reduce the risk of an
accidental airbag deployment or on-board computer damage.
Battery gases are explosive! Avoid sparks and do not smoke while working
near the vehicle's battery!
Always protect wires ran through the firewall from sharp metal edges and
hot parts of the engine! Always fuse positive wires at the battery or power
source!
INSTALLATION INSTRUCTIONS
8
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 start-
ing 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 modulewires are required, while others areoptional. Before starting
the installation, it should be determined 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 RS control module, which is mounted upon completion of the installation.
ThisRemoteStart Unitduplicatesthe actions thatoccurwithin the ignitionswitch
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 igni-
tion switch wires usually are high amperage circuits, which means that high reli-
ability connections must be made! We recommend proper soldering of all con-
nections.
Caution! Avoid the Airbag circuit! Especially avoid any harness or wires en-
cased 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. 9
Red Wire: (Two 12-Gauge wires) Connection Required
Connect both Red wires to constant 12 Volts. The most common sources are
the battery's Positive terminal and the ignition switch wiring harness (See diagram
#1).

Green Wire: 12-Gauge Connection Required
Connect the Green wire to the vehicle's Starter Motor wire. This wire will show
12 volts only when the ignition key is in the "Start" position. This wire is also found
in the ignition switch wiring harness (Seediagram #1 on page9). Some vehicles have
a second Starter wire known as a "Cold Start" wire. When this is encountered, if
the two Starter wires are the same circuit you may connect both of these wires to
the Green wire. If the two Starter wires are separate circuits an optional prewired
dual relay socket and relays are recommended.
Note: If a security system is present which utilizes a starter interrupt circuit, the
Green wire must be connected to the Starter Motor side of the interrupt.
Blue Wire: 12-Gauge Connection Required
Connect the Blue wire to the vehicle's Ignition #1 wire (also known as Primary
Ignition). This wire will show 12 Volts when the ignition key is in the "Run" and
"Start" positions and no voltage in the "Off" and "Accessory" positions. This wire is
found in the ignition switch wiring harness (See diagram #1).
Note: IftwoormorePrimaryIgnition wires are present, you will need to connect an
optional relay(s) to the thin Blue wire located in the 3-pin Blue connector (See
diagram #2 on page 13).
11
Yellow Wire: 12-Gauge Connection Required
Connect the Yellow wire to the vehicle's Accessory wire. This circuit supplies
power to the Heat, Ventilation and Air Conditioning (HVAC) system. This wire will
show 12 Volts when the ignition key is in the "Run" and "Accessory" positions and
No voltage in the "Start" and "Off" positions. The connection point for this wire is
also found in the ignition switch wiring harness (See diagram #1).
Note: If two or more Accessory wires are present, you will need to connect an
optional relay(s) to the thin Yellow wire located in the 3-pin Blue connector (See
diagram #3 on page 13).

Dark Blue Wire: Connection Required
The hood pin switch must be installed. It prevents operation of the RS unit
if the hood is open.
Connect the Dark Blue wire to the hood pin switch. Carefully route the Dark Blue
wire through the firewall, using an added or existing grommet. Avoid any hot or
moving parts. Mount the switch so that it is open (pin down) when the hood is shut
and closed (pin up) when the hood is open.
If there is an existing hood pin switch for an alarm system, you may use it for
the Dark Blue wire connection; diode-isolation is recommended.
Insteadof using a pin switch to monitor the hood's open orshut status, anOmega
AU-46 Mercury Tilt Switch may used. Connect one of the AU-46's wires to Nega-
tive Chassis Ground and connect the remaining wire to the Dark Blue wire.

Remote Start Override Mode:
The RS unit can be placed into an "Override" mode which will prevent it from
starting the vehicle. This mode is for situations when it is not convenient or safe
for the Remote Start feature to be operable. For example during extended stop-
overs for vehicle servicing, maintenance, valet parking, washing, etc.
Connect the Dark Blue wire to one of the included toggle switch's two wires. Con-
nect the toggle switch's remaining wire to ground.

Yellow/Black Wire: Connection
Required
The Yellow/Black wire must be connected. It is part a critical safety feature
which disables the RS unit whenever the brake pedal is pressed.
Connect the Yellow/Black wire to the brake switch wire which shows 12 Volts
when the brake pedal is pressed. The brake switch is typically located above the
brake pedal, and usually mounted to the brake pedal support bracket. Always
make this connection in a fashion ensuring its long-term reliability; soldering is
highlyrecommended. UponcompletingtheYellow/Blackwire's connection, thor-
oughly test the operation of this circuit.
Pink Wire: Connection If Desired
The Pink wire activates the RS Unit. If the Pink wire receives a Negative
pulse, the RS unit will start the vehicle's engine, provided that all safety circuits
are in the proper status. After the engine has been started by remote control,
another Negative pulse on the Pink wire will turn the RS unit off, stopping the
engine.
Connect the Pink wire to an available auxiliary output of an existing Remote
Security or Keyless Entry System.
21
Orange/Black Wire: Connection Required
The Orange/Black wire is the engine detect wire. The RS unit utilizes three
different methods of monitoring the vehicle during the remote starting process.
Considerallmethodsbeforedecidingwhichoneto use. Normally the Smart Start
method is used.
1) Vacuum Switch Sensing:
This method uses a Vacuum switch to verify that the vehicle' engine is running.
The Orange/Black wire connects to one of the Vacuum switch's wires, the other
wire is connected to chassis Ground. Connect the Vacuum switch using a "T"
connector to a vacuum hose on the engine's intake manifold.
1) Position the 3-way selector switch for Vacuum switch operation (right position).
2) Locate the Smart Start & Tach Sense adjustment screws and LED indicators.
3) Turn BOTH adjustment screws completely counterclockwise.
Note: Using a multimeter set to Ohms, measure the resistance of the Vacuum
switch. The switch should read Zero resistance when the engine is "Off" and
read Maximum resistance (open circuit) when the engine is running. If this is not
the case, relocate the vacuum connection.

22
2) Smart Start:
This method uses a voltage sensing circuit which reads the vehicle's voltage be-
fore attempting to start, and then monitors for a voltage increase which occurs
whenthealternatorhasoutput.TheOrange/Blackwireconnectstoaconstant12
Volt source (i.e.: the vehicle's battery).
Note: When using this method Programmable Jumper #3 will increase/decrease
the starter motor cranking time.
1) Position the 3-way selector switch for Smart Start (center position).
2) Locate the Smart Start & Tach Sense adjustment screws and LED indicators.
3) Turn BOTH adjustment screws completely counterclockwise.
4) Start the vehicle.
5) Begin tuning the Smart Start adjustment screw slowly clockwise until the LED
indicator begins to flash. The flashes confirm that the unit is sensing the en-
gine.
6) Turn the vehicle Off.
7) Confirm that the unit is not picking up noise from other vehicle circuits:
a. Without starting the engine, turn the ignition key to the "On" position.
b. If the LED indicator remains "Off" the unit has been properly tuned.
c.Ifthe LED indicator flashesthereisnoise on the Orange/Blackwire'sconnec-
tion and it will be necessary to relocate the connection. 23
3) Tach Sense:
If the vehicle is generally hard to start (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) information 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.
Note: When using this method Programmable Jumper #1 will increase/decrease
the unit's sensitivity.
1) Position the 3-way selector switch for Tach Sense (left position).
2) Locate the Tach Sense & Smart Start adjustment screws and LED indicators.
3) Turn BOTH adjustment screws completely counterclockwise.
4) Start the vehicle.
5) Begin tuning the Tach Sense adjustment screw slowly clockwise until the LED
indicator illuminates solid, then turn the vehicle Off.
- To increase the crank time, tune the adjustment screw counterclockwise.
- To decrease the crank time, tune the adjustment screw clockwise.
24
Orange Wire: Connection If Desired
