Wiring Connections

BLACK WIRE - (Ground): The function of the black wire is to supply

the system with (-)negative chassis ground.

Connect the Black wire to a clean solid chassis ground using a crimp-on

ring terminal. Scrape the metal surface to remove any rust, paint, grease, or

debris. Do not ground alarm to the vehicles battery or dashboard screws.

Note: If the ground connection is insufficient, the system can find partial

ground through other connections. In this case the system may partially

function, possibly arming & disarming, but would otherwise operate

erratically giving the impression of being defective.

Warning: Do NOT ground the single black wire attached to the brain. This

is the systems antenna wire. Grounding the antenna wire will severely

affect the systems operating range.

Example #2 Grounding The Black Wire To Sheet Metal: Running the screw through

two layers of sheet metal allows more threads to contact the metal, which reduces the chances

of the screw to strip out or become loose. Grind the surface until the metal is shiny and clean.

-Avoid trying to drill through the spot welds, which are harder than the surrounding metal.

Example #1: An existing machine-

threaded bolt that holds large structural

pieces of the dash frame to the vehicle's

framing structure may be used.

RED WIRE - (Positive +12 Volt Input): The function of the Red wire is

to supply the system with a constant source of (+)12 volts.

Connect to a constant (+)12 volt positive wire located in the primary wire

harness coming from the key switch.

-A connection here insures a good power source which is critical for correct

unit operation.

 Do not connect behind a vehicle fuse or to the vehicles battery.

 It is recommended that the red wire be the final system wiring connection.

Access to the ignition switch harness on most cars is obtainable by removing

the underdash "hush panels" and/ or the lower dash trim panels. On some

vehicles, notably General Motors and Ford/Lincoln/Mercury products, the

electrical part of the ignition switch is mounted on top of the steering column,

near its base. This switch is connected to the mechanical part (where the key

is inserted) by a linkage rod. Other vehicles, such as Chrysler, Dodge,

Plymouth and the vast majority of imports, the electrical and mechanical parts

are together, which means that the ignition switch is high in the steering

column, and that the lower steering column trim may need to be removed. If

soldering this connection, as recommended, solder quickly with the proper iron

and be aware that a heat sink may be needed to prevent excess heat in the wire

from damaging the ignition switch.

YELLOW WIRE - (Ignition Input): The function of the yellow wire is to

supply the alarm with a (+)12 volt signal Only when the vehicles ignition

key is turned to the On & Start positions. The alarm verifies whether

the vehicles engine is running or turned Off  through this line.

Connect the Yellow wire to a key switched (+)12 volt ignition wire

located in the primary wire harness coming from the key switch.

-The vehicles ignition wire will show (+)12 volts only when the vehicles

ignition key is turned to the On & Start positions.

-The ignition wire will Not drop out while the starter motor is cranking.

-If the key is turned off so is the vehicles ignition wire.

BROWN WIRE - (Positive Siren Output): The function of the Brown wire

is to supply a (+)12 volt output directly to the electronic siren when the alarm

is triggered and for confirmation chirps.

-Connect the systems Brown wire directly to the siren's Red wire.

-Connect the sirens Black wire directly to (-)chassis ground.

Warning: If the Brown wire touches ground damage will occur to the alarm.

ORANGE WIRE - (Ground Output For Starter Interrupt): The function

of the Orange wire is to provide one side of the included starter-disable relays

coil with a Constant 500ma (-)Ground Signal only while the system is Armed.

The other side of the relays coil will be supplied with a Key switched (+)12

Volts only when the ignition key is turned to the "start" position. This circuit

will prevent the vehicle from being started only while the system is Armed, and

will draw current from the vehicle's electrical system only if an attempt is made

to start the vehicle while the system is Armed.

CONNECTION: Locate and cut the vehicles starter motor wire.

-The starter motor wire will read (+)12 Volts only while the starter motor is actually

cranking. (When the vehicles ignition key is turned to the Start position)

-Cut this wire at a suitable location. Confirm that this is the correct wire by turning

the ignition key to the "Start" position. The starter should Not crank.

-Connect the starter-disable socket's Red wire to the key switch side of the cut starter

motor wire.

-Connect the starter-disable socket's White wire to the motor/solenoid side of the cut

starter motor wire.

-Connect the systems Orange wire to the Orange wire of the starter-disable socket.

Note: Be sure that good, solid electrical connections are made since the starter motor

circuit is generally a high amperage circuit.

WHITE WIRE - (Positive Flashing Light Output): The function of the

White wire is to supply a pulsed (+)12 Volt signal to flash the vehicles exte-

rior parking-lights in order to attract attention to the vehicle if the security

system is triggered and as a means of visually confirming system operations.

Connect the White wire to the vehicle's Positive 12 Volt parking-light circuit.

-The correct wire will show (+)12 Volts only when the headlight switch is in

the "Parking Light" and/or "Head Light" positions.

-This wire can usually be found at the headlight switch, the fuse/junction

block, or in the rear body harness in the driver side kick panel.

Note #1: When such a wire is located, be sure to also test that it is non-

rheostated: While metering the wire, operate the dash light dimmer control.

The correct wire will show no change in voltage when the dimmer is operated.

Note #2: Some vehicles, notably Toyotas, have a parking-light relay which is

triggered by a (-)Negative Ground signal from the headlight switch. In these

vehicles the White wire must be connected to the parking light circuit after the

relay, usually at the Fuse/Junction Block.

WARNINGS:

-If the White wire touches ground, damage will occur to the system.

-Do NOT connect the systems parking-light output wire to the vehicles

dash-dimmer circuit. Damage could occur to the vehicle and the unit.

-Do NOT directly flash the vehicles headlights. Damage can occur to the

unit since the high-amperage headlight circuit draws more current than

what the unitss on-board relay can provide. An external relay is required.

-Do Not flash Halogen headlights. Halogen type bulbs are not designed for

flashing applications and may therefore burn out prematurely.

Many European imports have separate left & right side parking light

circuits. When left & right parking lights are on separate circuits, a pair

of 6 to 10 amp diodes or a pair of relays must be used to connect the

White wire to each parking light side. Refer to diagrams.

GREEN WIRE - (Negative Door Trigger): The function of the Green

wire is to supply the system with a (-)negative ground signal only when a

vehicle door is open. The Green wire circuit is an instant trigger zone

whose connection is vital for many system operations such as Last Door

Arming, Automatic Rearming, Ignition Auto-Lock/Unlock, and door-zone

protection.

Connect the Green wire to the vehicles (-)pin-switch/dome-light circuit

which is common to all doors.

-The (-)negative ground type pin-switch/dome-light circuit will show

ground Only when a vehicle door is open. This circuit may possibly also

show up to (+)12 volts when all the doors are closed. The correct wire will

show this change when any vehicle door is opened & closed.

Note #1: If there is a dome-light delay, the pin-switch/dome-light circuit

may show (-)ground for the duration of the delay. In this case the Last Door

Arming Feature will wait until the dome-light has turned Off before

beginning the self-arming countdown. The open zone bypass feature will

allow the system to be actively Armed using a remote control while the

dome-light delay is On and will start protecting the Green wire circuit 5

seconds after the dome-light turns off.

Note #2: In vehicles equipped with dash displays or door ajar warnings,

all of the doors may be diode-isolated from each other. Do Not bridge all of

the door pin-switches together. In this case it is necessary to connect the

Green wire to the wire which directly feeds the vehicles dome-light.

VIOLET WIRE - (Positive Door Trigger): The function & characteristics of

the Violet wire are identical to those of the Green Door Trigger wire, with the

sole exception that the Violet wire is for use in vehicles equipped with a positive

(+)12 volt door pin-switch/dome/light circuit (i.e.: some Fords). In these

vehicles the Violet wire will supply the system with a (+)12 volt signal only

when a vehicle door is open.

Connect the Violet wire to the vehicles (+)pin-switch/dome-light circuit

which is common to all doors.

-The positive (+)12 volt pin-switch/dome-light circuit will show (+)12

volts Only when a vehicle door is open. This circuit may possibly also

show (-)Ground when all the doors are closed. The correct wire will show

this change when any vehicle door is opened & closed.
