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). If extended wires are needed, they must be exactly the 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.
f). Connect the ORANGE wire (pin #85) of the relay to a switched 12 volts source from the ignition switch.
NOTE: If more than one electronic device will be connected to the ORANGE Wire, it will be necessary to
isolate the connection of each device control wires with a 1N4003 diode.

H8/6. Brown / Black wire
– (-) 200mA Horn Output –
This wire is provided to use the existing vehicle's horn as the alarm system's optional warning audible
device. It's a transistorized low current output, and should only be connected to the low current ground
output from the vehicle's horn switch. When the system is triggered, the horn will sound.
H8/7. Light Green / Black wire
– (-) 200mA 2-Step Door Unlock Output –
The 2-step door unlock feature will work for the most fully electronic door lock circuit. The vehicle must
have an electronic door lock switch (not the lock knob or key switch), which locks and unlocks all of
vehicle's doors. When wired for this feature, pressing the disarm (or unlock) button one time will disarm
the alarm and unlock the driver's door only. If, you press the disarm (or unlock) button two times within 3
seconds, the alarm will disarm and all the doors will unlock.
H8/8 Purple / Black wire
– (-) 200mA Channel 4 Programmable Output –
This wire is built-in user-programmable timer output provides a ground through this wire. Press the
transmitter
and
or F buttons at the same time. You may program the built-in timer to send a
ground signal for any time interval between 1 second and 2 minutes. For instance, this timer output may be
used to turn on the headlight with the remote control. Also on certain BMW, Mercedes Benz, Jaguar and
Volkswagen cars, you can use this unique timed output to allow remote closure of all power window and
sunroof without the need for an external module!
H8/9. Red / White wire
– (-) 200mA Channel 3 (Trunk) Output –
This will become a 1 second pulse ground by activating channel 3 on the transmitter for two seconds. The
current capacity of this wire is 200mA. This feature allows you to remote control the trunk release or
another electric device. This output can also be programmed to provide the following type of output:
1-second pulse, latched, timer control, and pager. (See Alarm Feature

H8/10.Black / White wire
– (-) 200mA Dome Light Control Output –
This wire becomes grounded when the dome light control circuit is active. The current capacity of this wire
is 200mA. This wire can control the operation of the interior lights. An optional 10 Amp relay can be used
on this system for interior lights operation.
a). Upon disarming, the interior lights will remain on for 30 seconds.
b). If the vehicle is violated, the interior lights will flash for the same duration as the siren.
