WIRING
Keep wiring away from moving engine parts, exhaust pipes, and high-tension cable. To prevent fraying, tape
wires that pass through holes on the firewall. Watch out for sharp edges that may damage wires and cause
short circuit.
CAUTION: Do not connect the wiring harness to the control module until all wiring to vehicle is complete.
H1: MAIN 5 PIN WIRE HARNESS:
H1/1. Red / White wire –Parking Light Relay Input –
The RED/WHITE wire is the input to the flashing parking light relay. The connection of the RED/WHITE
wire will determine the output polarity of the flashing parking light relay.
If the vehicle you are working on has +12 volt switched parking light, you do not need to connect this wire.
This wire is already connected to +12 volt.
If the vehicles parking light is with a ground switched, cut the RED/WHITE wire, connect the RED/WHITE
wire to chassis ground.
H1/2. White wire –Parking Light Relay Output (+12 V 10A Output) –
Connect the WHITE wire to the parking light wire coming from the headlight switch. Do not connect the
WHITE wire to the dashboard lighting dimmer switch. (Damage to the dimmer will result). The limitation of
the WHITE wire is 10 Amp max. Do not exceed this limit or damage to the alarm and parking relay will
result.
H1/3. Black wire –System Ground –
This is main ground connection of the alarm module. Make this connection to a solid section of the
vehicle frame. Do not connect this wire to any existing ground wires supplied by the factory wire loom.
Make the connection to the vehicle's frame directly.
H1/4. Brown wire –Siren Drive or Horn Output –(Set Feature III –1 Programming)
SIREN DRIVE OUTPUT (Factory default setting)
This is the positive (+) output connection for the siren. Current capacity is 2 Amp. Make connection to
the (+) red wire from the siren. Make the (-) black wire coming from the siren to a good chassis ground.
(+) Low Current HORN OUTPUT -- (Set Alarm Feature III –1 To Horn Output)
This wire is provided to use the existing vehicle's horn as the alarm system's optional warning audible
device. It is a transistorized low current output, and should only be connected to the low current positive
(+) output from the vehicle's horn switch.
H1/5. Red wire –System Power (+12V Constant) –
The RED wire supplies power to the system. Connect this wire to a constant +12 volt source.

the connection of the GREEN Wire here.
H3/4. Yellow wire –To Ignition Switched +12V –
This wire is connected to a switched 12 volts source. This wire should receive "12 volts" when the ignition
key is in the "ON" and "START" position. When the ignition is turned "OFF", this wire should receive "0"
volts.
H3/5. Orange wire –(-) 200mA Grounded Output When Armed –
This wire will become grounded when the alarm is armed. The current capacity of this wire is 200mA. This
output can control a starter disable. When an intrusion is detected and the system is triggered, the vehicle
is prevented from any unauthorized starting.
a). Find the wire from the starter solenoid, (usually located on the starter) and going to the ignition switch.

MEGA 474L

b). When found, use voltmeter, connect one probe of the voltmeter to ground and connect the other end of
the probe to the starter wire, it should receive "12 volts" only when the ignition key in the "START"
position.
c). After locating the correct wire, cut it in half, try to start the vehicle. The engine should not "crank over".
d). When the extend wires are needed, they must be exactly same gauge as the cut wire. Connect the cut
wire from the key switch to the RED wire (pin #30) of the relay, and connect the starter wire to the
WHITE wire (pin #87a) of the relay.
e). Connect the ORANGE Wire from the control module to the ORANGE wire (pin #86) of the relay.
