Primary Harness Wiring Instructions
This guide describes in detail the connection of each wire. Also included are possible applications
of each wire. This system was designed with the ultimate in flexibility and security in mind. Many
of the wires have more than one possible function. Please read carefully to ensure a thorough under-
standing of this unit.
H1/1 ORANGE (-) ground-when-armed output
This wire supplies a (-) ground as long as the system is armed. This output ceases as soon as the
system is disarmed. The orange wire is pre-wired to control the 8618 starter kill relay. It can supply
up to 500 mA of current.
NOTE: If using the H1/1 ORANGE wire to activate an add-on accessory such as window
automation, pager or voice module a 1Amp diode must be installed to ensure proper operation.
Insert the diode as shown in the following diagram.
RED/WHITE (-) 200 mA Channel 2 Output
RED (+) Constant Power Input
BROWN (+) Siren Output
YELLOW (+) Switched Ignition Input, Zone 5
BLACK (-) Chassis Ground Input
VIOLET (+) Door Trigger Input, Zone 3
BLUE (-) Instant Trigger Input, Zone 1
GREEN (-) Door Trigger Input, Zone 3
BLACK/WHITE (-) 200 mA Domelight Supervision Output
WHITE/BLUE (-) 200 mA Channel 3 Programmable Output

H1/2 WHITE (+/-) light flash output
As shipped, the H1/2 WHITE wire should be connected to the (+) parking light wire. If the light flash
polarity jumper is moved to the (-) position (see the
Programming Jumper section of this installation
guide), this wire supplies a (-) 200 mA output. This is suitable for driving (-) light control wires in
Toyota, Lexus, BMW, some Mitsubishi, some Mazda, and other models.
NOTE: For parking light systems that draw 10 amps or more, the jumper must be switched to a
(-) light flash output (see the
Programming Jumpers section of this guide). P/N 8617 or a standard
automotive SPDT relay must be used on the H1/2 light flash output wire.
IMPORTANT! DO NOT connect this wire to a negative vehicle light flash wire before
changing the programming jumper to the negative polarity position or damage to
vehicle light circuit may occur.
IMPORTANT! Never interrupt any wire other than the starter wire.

H1/3 WHITE/BLUE 200 mA (-) channel 3 output
This wire provides a (-) 200 mA output whenever the transmitter button(s) controlling channel
three is pressed. This output can be programmed to provide the following types of output (see
System Features Learn Routine section of this guide):
➤➤A vvaalliiddiittyyoutput will send a signal as long as the transmission is received.
➤➤A llaattcchheeddoutput will send a signal continuously when the channel three button(s) is pressed and
released. The signal will continue until channel three is pressed again.
➤➤A llaattcchheedd//rreesseettwwiitthhiiggnniittiioonnoutput works similar to the latched output, but will also reset
(output will stop) when the ignition is turned on and then off.
➤➤A 3300sseeccoonnddttiimmeeddoutput will send a signal for 30 seconds when channel three is pressed. This
output can be shut off during the 30-second period by pressing Channel 3 again.
➤➤This output can also be programmed to provide a sseeccoonndduunnlloocckkppuullsseewhen the unlock button
is pressed a second time after disarming the system. This can be used to unlock the passenger
doors when installing progressive door locks.
H1/4 BLACK/WHITE (-) 200 mA domelight supervision output
Connect the H1/4 wire to the optional domelight supervision relay as shown in the following
diagram:
IMPORTANT! This output is only intended to drive a relay. It cannot be connected
directly to the domelight circuit, as the output cannot support the current draw of one
or more bulbs.
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input!
This transistorized output can only supply 200 mA, and connecting directly to a
solenoid, motor, or other high-current device will cause the module to fail.

H1/5 GREEN (-) door trigger input
Most vehicles use negative door trigger circuits. Connect the green wire to a wire showing ground
when any door is opened. When connecting to newer model vehicles there is generally a need to use
individual door triggers. See DirectFax document 1076 for wiring instructions. This wire will report
Zone 3.
NOTE: If using a door trigger wire that has a delay, Advanced Menu 2, feature 6 or the 998T
Bitwriter
®
can be used to turn Bypass Notification off.
H1/6 BLUE (-) instant trigger input
This input will respond to a negative input with an instant trigger. It is ideal for hood and trunk pins
and will report on Zone 1. It can also be used with Directed single-stage sensors. The H1/6 blue
instant trigger wire can also be used to shunt sensors during operation of auxiliary channels or remote
start. (See
Bypassing Sensor Inputs section of this guide.)
H1/7 VIOLET (+) door trigger input
This type of dome circuit is used in many Ford products. Connect the violet wire to a wire that shows
(+)12V when any door is opened. This wire will report Zone 3.
NOTE: If using a door trigger wire that has a delay, Advanced Menu 2, feature 6 or the 998T
Bitwriter
®
can be used to turn Bypass Notification off.

H1/8 BLACK (-) chassis ground connection
Connect this wire to a clean, paint-free sheet metal location (driver kick panel) using a factory bolt
that DOES NOT have any vehicle component grounds attached to it. A screw should only be used
when in conjunction with a two-sided lock washer. Under dash brackets and door sheet metal are
not acceptable ground points. It is recommended that all security components be grounded at the
same location.
H1/9 YELLOW (+) ignition input
Connect this wire to the (+) 12 volts ignition wire. This wire is pre-wired to the starter kill relay and
must show (+) 12 volts with the key in RUN position and during cranking. Take great care that this
wire cannot be shorted to the chassis at any point.
\\\\\\\
H1/10 BROWN (+) siren output
Connect this to the RED wire of the Revenger
®
siren. Connect the BLACK wire of the siren to (-)
chassis ground, preferably at the same point you connect the control module’s BLACK ground wire.

H1/11 RED (+)12V constant power input
Before connecting this wire, remove the supplied fuse. Connect to the battery positive terminal or
the constant 12V supply to the ignition switch.
NOTE: Always use a fuse within 12 inches of the point you obtain (+)12V. Do not use the 15A
fuse in the harness for this purpose. This fuse protects the module itself.
H1/12 RED/WHITE 200 mA (-) channel 2 output
When the system receives the code controlling channel 2 for longer than 1.5 seconds, the
RED/WHITE will supply an output as long as the transmission continues. This is often used to
operate a trunk/hatch release or other relay/driven function.
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input!
The transistorized output can only supply 200 mA of current. Connecting directly to a
solenoid, motor, or other high-current device will cause it to fail.

NOTE: For detailed instructions about connecting to the vehicle’s power door lock systems, refer
to the Door Lock Wiring guide (Document No. 1041) available to authorized dealers only from the
technical resources listed at the front of this guide.
Peripheral Plug-In Harnesses
Super Bright LED, 2-Pin WHITE Plug
The super bright LED operates at (+) 2 volt DC and plugs into the two-pin WHITE port. Make
sure the LED wires are not shorted to ground as the LED will be damaged. Multiple LED’s can be
used, but they must be wired in series. The LED fits into a 9/32-inch mounting hole. Be sure to
check for clearance prior to drilling the mounting hole.
DIA-41
IMPORTANT! The door lock outputs are low current and should not be attached
directly to any high current device; they are only to be used to activate relays
