INSTALLATION OF THEMAJORCOMPONENTS

ControlModule:

Select a mounting location inside the passenger compartment (behind the dashboard). The mounting location

selected must be within 24" of the ignition switch wiring harness to allow connection of the 6-pin harness. Be

certain that the chosen location will not interfere with the proper operation of the vehicle. Avoid mounting the

module to or routing the wiring around the steering shaft/column, as the module or wiring may wrap around or

block the steering wheel preventing proper control of the vehicle. Secure the module in the chosen location

using cable ties or screws as necessary. Do not mount the module in the engine compartment, as it is not

waterproof.

HOODPINSWITCH:

The pin switch included in this package is required for the safety shut down of the Remote Start system. If the

vehicle is being serviced, this hood switch prevents the remote start activation even if the transmitter is

operated. This switch MUST be installed in all applications. Failure to do so may result in personal injury or

property damage. Mount the switch in an area under the hood that is away from water drain paths. If necessary,

the included brackets may be used to move the switch away from rain gutters or allow mounting to the firewall

behind the hood seal. In either case the switch must be set to allow the hood to depress the switch at least 1/

4" when the hood is closed and fully extended when the hood is opened. For direct mounting, a 1/4" hole must

be drilled. Carefully check behind the chosen location to insure the drill will not penetrate any existing factory

wiring or fluid lines. Drill a 1/4" hole in the desired location and thread the pin switch into it. If using the

mounting bracket, first secure the bracket to the desired location and secure the pin switch in the threaded

mounting bracket hole.

The CA-421 is to be used in vehicles with AUTOMATIC TRANSMISSIONS only! Although this is a sophisticated

system with many advanced features, IT MUST NOT be installed into a vehicle with a manually operated

transmission. Doing so may result in serious personal injury and property damage.

IMPORTANT!

DO NOT PLUG THE SIX PIN OR THE MULTI PIN HARNESS INTO THE CONTROL MODULE UNTILALL

CONNECTIONS.

WIRINGTHE6PINHARNESS:

RED: +12 volts

RED: +12Volts

Connect these wires to a +12 Volt constant source found at the vehicle's ignition switch using the 30 Amp

fuses and holders provided. Most vehicles have more than one battery source supplying power to the ignition

switch. Separate feed wires must be used for both of the RED wires. If your vehicle does not have two battery

feed wires at the ignition switch then it is possible to connect both wires to the vehicle's battery.

IMPORTANT!

It is the responsibility of the installing technician to determine the load factor of the vehicles electrical circuits

when the vehicle is running and to adequately fuse the two power wires based on that load.

PURPLE: Starter Output

This wire will have +12 volts when the ignition switch is turned to the start (crank) position only. This wire will

have 0 volts in all other ignition switch positions.

PINK: Ignition 1 Output

Connect this wire to the ignition 1 wire from the ignition switch. This wire will show +12 volts when the ignition

key is turned to the to the ON, RUN and START positions, and will have 0 volts when the key is turned to the OFF

and ACCESSORY positions. For Diesel Applications, this wire must be connected to the ignition circuit that

powers the glow plugs if the vehicle requires glow plug pre-heating. (See programmable features #8)

PINK w/ WHITE: Ignition 2 Output*

Connect this wire to the ignition 2 wire from the ignition switch. This wire will show + 12 volts when the ignition

key is turned to the ON or RUN position and in some cases the START position. This wire will show 0 volts

when the key is turned to the OFF and ACCESSORY positions.

*NOTE: See programmable features #2 for programming this wire to function as an ACCESSORY wire.

ORANGE: AccessoryOutput

Connect this wire to the Accessory wire from the ignition switch. This wire will show + 12 volts when the ignition

switch is turned to the ACCESSORY, ON and RUN positions, and will show 0 volts when the key is turned to the

OFF and START positions.

WIRINGTHE12 PIN HARNESS:

BLACK: Chassis Ground Source

Connect the BLACK wire to a known vehicle ground source or to a solid clean metal part of the chassis. Be

certain to remove any paint or grease and secure this wire with a self taping screw and ring terminal.

BLACK w/WHITE: NeutralSafety Input (-)

The BLACK w/ WHITE neutral safety input is required for remote start operation. Connect the BLACK w/WHITE

wire to the vehicle wire at the shifter that will show ground when in park or neutral, and voltage in all other

positions.

GRAY: Hood Pin Input (-)

Connect the GRAY wire to the hood pin switch provided. This wire will be routed through the firewall into the

engine compartment. It is necessary to use an existing grommet when passing wires through the firewall to

prevent short circuiting. This is an important safety feature of CA 421, and failure to use this feature can result in

serious injury. Route the wire to the pin switch and connect it using the bullet connector provided.

BROWN w/ RED Wire: Positive Brake Input

Any time +12 Volts is applied to the BROWN w/RED wire, the Remote Start system will stop operating, even if

the signal is received from the transmitter. If the brake light switch in the vehicle switches +12 Volts to the brake

light circuit, connect the BROWN w/RED wire to the output of the brake light switch. If the brake light switch in

the vehicle switches ground, do not use the BROWN w/RED wire; see GRAY w/BLACK wire.

Note: The BROWN w/RED wire is used for programming, if the brake switch in the vehicle switches ground, a

normally open push-button switch must be added. During the program sequence, when the brake pedal is

pressed and released, this switch will be used in it's place. If the installation of this switch is necessary,

connect one end of the normally open push button switch to the BROWN w/RED wire, and connect the other

end of the switch to a fused +12 volt source.

Brake Switch Positive Shutdown Detail

YELLOW w/ BLACK: + 12 VoltAlarm By - Pass Output

This wire provides a 500mA +12 Volt transistorized output when the ignition key is turned to the ON position, and

0 Volts when the ignition key is OFF and when the vehicle is running under the control of the Remote Start. This

wire should be connected to the ignition input of the alarm system. The YELLOW w/BLACK wire output will allow

you to Remote Start the vehicle while leaving the alarm armed, and to lock/unlock the doors while running

under control of the remote start system.

WHITE/RED and WHITE Wires: Parking Light Output

These wires are the COMMON and NORMALLY OPEN contacts of the on-board parking light relay. If the

vehicle's parking lights are a +12 volt switched system, connect the WHITE/RED wire to a fused (15A max.) +12

volt battery source, and connect the WHITE wire to the vehicle's parking light wire. If the vehicle's parking lights

are a chassis ground switched system, connect the WHITE/RED wire to a chassis ground source, and connect

the WHITE wire to the vehicle's parking light wire.

BLUE w/BLACK:Active output (-) Ignition 3 / Shock Disable Output

This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start system

initializes, and remains grounded while running plus an additional 4 seconds after the Remote Start system

turns off. In all of the applications described below, a relay will be required. The BLUE w/BLACK wire can be

used to accommodate the following situations:

1. Shock Sensor Bypass:

If there is Shock Sensor used with an alarm system and it is not shunted during the Remote Start activation

period, then vibration from the running vehicle can cause the alarm to trigger. In this case, connect the Blue/

Black Wire to terminal #86 of a external relay. Connect terminal# 85 of the relay to a fused + 12 volt battery

source. Cut the shock sensor trigger wire and connect one end of the cut wire to terminal #30 and the other end

of the cut wire to terminal #87a. Just before the Remote Start system is activated, the relay contacts will open,

preventing the shock sensor's operation until the Remote Start system shuts off.

2. Ignition 3 Output:

Some newer vehicles use a third ignition wire which is required to start and keep the vehicle's engine running.

If this is the case, connect the BLUE w/BLACK wire to terminal #86 of an external relay. Connect terminal # 30 &

# 85 to a fused + 12 volt battery source rated for a minimum of 25 Amp. Connect terminal # 87 to the third

ignition wire in the vehicle.

3. Transponder Key Override:

To bypass the system while the vehicle is operating under the control of the Remote Start system. Connect the

BLUE w/BLACK wire to the NEG trigger input of the accessory bypass.

GRAY w/BLACK: Diesel WaitTo Start

For Diesel glow plug preheat circuits, this Wait To Start input will allow the ignition to keep the glow plugs active

for the vehicles automatic time out period before cranking the starter motor. If the GRAY w/BLACK is connected

to the glow plug wire, this will take precedence over the timing setting and the Gas/Diesel programming in the

feature programming chart. Use this wire if you do not want to set the timing of the glow plug preheat circuit as

shown in the programmable features chart #8.

PURPLE w/WHITE: Tach Sensor Input

This wire will continually monitor the engine tach rate while the unit is under power of the Remote Start system.

This wire will be routed to the vehicle ECM tach input or through the firewall into the engine compartment and

connect to the negative side of the ignition coil. This Remote Start system learns the tach rate of the vehicle and

in most cases will operate properly from one multi coil pack regardless of the number of cylinders. If the vehicle

has a single coil system for each cylinder, it may be necessary to connect this wire to more than one coil for

proper tach reference. Shown in the programmable features chart #4.

WIRINGTHE4PINHARNESS:

This harness provides low current outputs to control various functions in the vehicle during different stages of the

Remote Start system's operation. Understanding these outputs and the time in which they occur will allow you to

determine if they are needed for the particular vehicle you are working on, as well as how to use them.

BLACK w/YELLOW: Ground Output During Start (Crank)

The BLACK w/YELLOW wire will provide a 300mA ground output while the starter output of the Remote Start

system is active. This output can be used to activate the Bulb Test wire found in some GM vehicles.

GREEN w/WHITE: Pulsed Ground OutputAfter Shutdown

The GREEN w/WHITE wire will provide a 1 second 300mA pulsed ground output after the Remote Start system

shuts down. This output will occur regardless of whether the circuit times out or is manually terminated.

Typically this output will be used to re-lock the vehicle doors if the doors unlock automatically when the ignition

circuit transitions to OFF.

BLUE: Pulsed Ground OutputAfter Start

The BLUE wire will provide a 1 second 300mA pulsed ground output after the vehicle is started under control of

the Remote Start system. Typically this wire will be used to re-lock the vehicle doors if the doors unlock

automatically when the factory anti-theft system is disarmed.

GREEN w/BLACK: Pulsed GroundOutput Before Start

The GREEN w/BLACK wire will provide a 1 second 300mA pulsed ground output 1.5 second before the remote

start system activates. Typical use for this output would be to disarm a factory theft deterrent system to prevent

false triggering of the factory alarm when the Remote Start system engages.

This output can also be used to unlock the doors while the vehicle is remote started. To unlock, press and hold

the transmitter button for 3 seconds while the vehicle is remote started. This feature is designed for vehicles

that have the factory keyless transmitter that does not function with the ignition on. To prevent the system from

unlocking the vehicle when the remote start cycle begins, wire the factory disarm / unlock output with a relay as

illustrated below.

2 Pin Blue Connector : Programming Button

Connect the 2 pin programming plug into the mating connector of the control module. Note the programming

button is built into the antenna.

3 Pin Antenna/Receiver Connector: (Black Connector)

Plug the previously routed three pin connector from the antenna receiver assemble into the mating connector of

the control module. This connector supplies 12 volts, ground and RF data from the antenna receiver to the

remote start module. Be certain this connector is firmly seated making good contact to the control system.
