PRE-INSTALLATION CONSIDERATIONS
BEFORE BEGINNING, check all vehicle manufacturer cautions and warnings regarding electrical service (AIR BAGS,
ABS BRAKES, ENGINE / BODY COMPUTER AND BATTERY).
PLAN OUT YOUR INSTALLATION and determine most suitable locations for all components to be placed. These
components include: the module itself, valet/program button, possible relays, and antenna/receiver (RS900/999FM only,
RS901 model does not include antenna or remotes.) Allow enough wire to create a service loop with strain relief, should
servicing be required. This will also allow easier access and mounting.
DAMAGE to the CoolStart unit resulting from incorrect installation or failure to follow guidelines stated in this book will
not be covered under warranty and will be subject to repair or replacement charges.
USE A VOLT/OHM METER to test and locate all connections. Test Lights can damage a vehicle’s computer systems.
ADDITIONAL PARTS, which are not included with this unit, may be needed for your particular vehicle. . These items
may include extra relays or Anti-Theft System Bypass modules.
INSTALLATION CAUTIONS & WARNINGS
**FOR SAFETY REASONS, DO NOT INSTALL RS900/901/999FM in vehicles with MANUAL TRANSMISSIONS.** If
accidentally left in gear, a remote started vehicle could become a self-propelled threat to life and property.
DO NOT extend the RS900/901/999FM Remote start ignition harness length. Mount the module so that main harness
reaches all ignition switch wiring. Extending these wires could result in poor or improper performance.
DO NOT route any wiring that may become entangled with brake, gas pedals, steering column or any other moving parts
in the vehicle.
DO NOT exceed the rated output current of any circuit on the Remote start module. Failure to observe this warning will
result in damage to the unit not covered under warranty.
DO NOT remote start the vehicle in a closed garage. Make sure that the garage door is open or there is adequate
ventilation. Failure to observe this rule could result in injury or death from poisonous Carbon Monoxide fumes.
WIRING
PIN 1: YELLOW/WHITE: (-) HORN CHIRP/HONK OUTPUT
Connect to the LOW CURRENT Negative Horn Trigger wire usually located near the steering column. If the vehicle horn
circuit requires +12V, then a relay is required. RELAY WIRING: Connect the Yellow/White wire to terminal #85, connect
relay terminals #86 and #87 to +12V constant power. Connect terminal #30 to the +12V positive Horn activation wire.
PIN 2: BLACK: MAIN SYSTEM GROUND
Connect to chassis metal of the vehicle. An existing bolt or screw may provide an adequate ground, or drill a small hole,
scrape away paint and attach using a sheet metal screw & star washer. This wire must be connected to a proper ground
or undesirable and inconsistent operation will occur. Do not use Factory ground locations.
This negative output wire is programmable and can function two different ways. It can be used as a Negative Ignition
output for GM Anti-theft and Transponder Bypass modules, or it can be programmed to function as an Anti grind/Starter
Disable output. As a Negative Ignition wire, this wire turns on when the remote start button is pressed and stays on
through the duration of the remote start. As an Anti grind/Starter disable this wire activates when the Lock button on the
remote is pressed and during remote start. When using this wire for an Anti grind/Starter disable, an optional Relay is
needed to interrupt the Starter circuit. The starter disable circuit adds an anti-theft feature to this remote start system
and prevents accidental grinding of the starter if key is turned to far after a remote start. See diagrams on NEXT PAGE.

WIRING
PIN 4: BROWN: (-) AUX OUTPUT (TRUNK POP) or DOME LIGHT ILLUMINATION OUTPUT
This output is programmable for two modes of operation. See Programming Option #9 Page 16.
Mode (1) DEFAULT: Provides a Ground pulse when button #3 (Trunk) on the remote transmitter is pushed to activate
a factory electric trunk release or other optional accessory.
Mode (2) ALTERNATE: Provides a Ground output for 30 seconds when the unlock button is pressed for use as a
dome light illumination output.
Note when using the Brown wire as a Trunk Pop, you may also need or want to program option #14 so the system
also provides an Unlock signal when the trunk pop is activated. This may help to prevent unnecessary triggering
of Factory Alarm systems or you may want the convenience of having the door unlock at the same.
See descriptions & diagrams below. See Programming Option #5 on page 16.
Mode (1) [Default (-) Neg. Start Activation] This wire
allows a host (or parent) alarm’s or keyless entry system
to activate a Remote Start by sending a 1-Second
Negative signal to the Green input wire to trigger a
remote engine start or stop. Connect the Green wire to
the host system’s Auxiliary channel output wire.
Mode (2) [Alternate OEM Interface] This mode allows
the system to Remote Start or Stop when 3 successive
Negative pulses are sent to the Green input wire.
Connect the Green input wire to the Negative lock signal
wire of the factory system. If your Factory OEM system
does not have this type of signal, then a relay is
required.
TURBO TIMER INPUT [No programming required] This
wire allows the system to keep a vehicle running for 1-5
minutes [selectively] after removing the key. This mode
requires the use of a momentary switch that is not
included with the kit. Connect a 2-pole momentary
switch with one side to chassis Ground and the other
side to the Green input wire. If you own a turbo or turbo
diesel vehicle, you can now allow the CoolStart system
to keep your engine running for 1-5 minutes after
exiting/locking your vehicle to cool-down without the
need for an external “Turbo Timer”.

WIRING
PIN 6: GRAY: (-) NEGATIVE HOOD PIN SWITCH
Connect the Gray wire to a switch that is at ground when the hood is open. If an existing switch is not available, then we
recommend one be installed. When this wire is grounded, the remote start is inhibited. If hood is opened on a remote
started engine, the unit will immediately shut the motor off. The unit will not attempt to start if hood is open. The hood
pin is also used for remote transmitter programming.
PIN 7: PINK: NEGATIVE or POSITIVE DIESEL GLOW PLUG or DOOR TRIGGER INPUT
Connect Pink wire to indicator circuit that shows a (- or +) Signal while the “WAIT TO START LAMP” is on. When this
wire is used, the RS900/901/999FM system will wait until light turns off before attempting a remote start. Note: This
input is jumper selectable for Positive or Negative type signals. See jumper pin diagram on page 23 for configuration.
PIN 8: PURPLE: (+12V) BRAKE RESET
Connect the Purple wire to the side of brake pedal switch that shows +12 volts ONLY when pedal is depressed. This is
the wire that turns off the remote start once the driver’s key is in the Ignition and turned to the ON position.
PIN 9: ORANGE/BLACK: (-) OEM DISARM OUTPUT
This wire provides a Ground pulse to disarm the vehicles' Factory anti-theft system prior to a Remote Start. Connect this
wire to the vehicles' anti-theft disarm wire. This wire is sometimes found coming off the Driver's door key switch or at the
Factory Anti-theft control module. This wire may not be needed if Factory Security only requires a door unlock pulse.
PIN 10: ORANGE: (-) OEM REARM OUTPUT
This wire provides a ground pulse to rearm the vehicles' FACTORY anti-theft system after a timed-out or aborted remote
start. Connect this wire to the vehicles' anti-theft rearm wire or to the door pin circuit depending on your requirements.
This wire may be needed to pulse the door pin circuit on vehicles with retained accessory power.
PIN 12: RED/WHITE: TACHOMETER INPUT
When installing the RS900/901/999FM in Tach mode, this wire must be connected to a valid source of AC voltage. This
wire allows the unit to sense the engine running and control the starter motor. See TACH REFERENCE MODE.
PROGRAM/OVERRIDE SWITCH: 2 PIN PLUG
This switch is used for programming features, transmitters, valet mode, and to override the optional starter disable (if
installed) in the event of a non-operating remote control.
LED: 2 PIN PLUG (OPTIONAL)
The LED is used as a VALET/PROGRAMMING indicator and it will also FLASH for use as security deterrent when the
optional ANTI-GRIND/STARTER DISABLE output is programmed.
WIRING: 7-PIN HIGH-CURRENT CONNECTOR
BROWN: +12V STARTER OUTPUT 30A:
Connect to circuit in the vehicle that has power ONLY while the STARTER MOTOR is CRANKING.
GRAY: +12V ACCESSORY OUTPUT 30A:
Connect to circuit in the vehicle that provides Accessory Power for systems such as HEAT and A/C. Typically, this wire
turns ON with the first position of the key, DROPS OUT WHEN CRANKING, then returns as the engine starts and runs.
(2) RED: +12V POWER INPUT WIRES (30A Fused):
Connect to both of these leads to +12V Constant Power. We recommend the BATTERY POSTIVE
TERMINAL.
PINK: +12V IGNITION OUTPUT 30A:
Connect to circuit in the vehicle that provides true Ignition Power for systems such as Spark and Fuel. Typically, this
wire turns ON with the second position of the key, STAYS ON WHEN CRANKING, and continues ON as the vehicle
runs.
This is an optional multi-function output wire the can be configured as a Second IGN, ACC or STARTER output. Some
vehicles require more than just one IGN, ACC, or STARTER wire in order to start and run successfully. If this is the
case for your particular vehicle, then use the jumper pin located under the access panel on the top of the CoolStart
control module to configure this wire to suit your needs. The DEFAULT setting is IGNITION. See Jumper Pin Diagram.
WHITE: +12V or (-) NEGATIVE PARKING LIGHT OUTPUT:
Connect to vehicle parking light circuit at the back of light switch or if this is not possible, connect directly to one of the
parking lights at the front of the vehicle. If your vehicle has a multiplex lighting system that requires a (-) Negative
parking light output, then open the access door on the top of the module and move the jumper. See Jumper Pin section.
Some European vehicles require separate left and right circuits. Use a dual relay or diodes to isolate the output. Note
the current limit on the Negative parking light output. You may require an external relay to prevent damage to the unit.
(1) Default parking light output is +12 volts.
(2) Use an external relay for vehicles that draw excess current from extra running lights, light bars, or trailers.
Parking light output is limited to +10 or -.5 AMPS only.
