Do not disconnect the battery if the vehicle has an anti-theft coded radio. If equipped
with an airbag, avoid disconnecting the battery if possible.
IIMMPPOORRTTAANNTT!!Please read this entire installation guide before beginning the installa-
tion. The installation of this security system requires interfacing with many of the vehi-
cle’s systems. Many new vehicles use low-voltage or multiplexed systems which can
be damaged by low resistance testing devices, such as test lights or logic probes. Test
all circuits with a high-quality digital multi-meter before making the connections.
IMMPPOORRTTAANNTT!!Many airbag systems will display a diagnostic code through their warn-
ing light after they lose power. Disconnecting the battery requires this code to be
erased, a procedure that can require a trip to the dealer.
before beginning the installation:
zCheck with the customer to determine the integrated LED/Valet switch location.
zRemove the domelight fuse. This prevents accidentally draining the battery.
zRoll down a window to avoid being locked out of the car.
after the install:
zTest all functions. The “Using Your System” section of the Owner’s Guide is very
helpful when testing.
zWhen testing, don’t forget that this system is equipped with Nuisance Prevention®Circuitry.
NPC™can bypass both instant trigger zones, making them seem to stop working.
zCarefully reassemble the under-dash trim panels.
zInspect the engine compartment for tools that may have been left behind.
tools required
This is a general list of tools required to complete the installation of this security sys-
tem in most vehicles. Some vehicles may require additional tools.

deciding on component location
control module
Never put the control module in the engine compartment!
The first step in hot-wiring a vehicle is removing the driver's side underdash panel to
access the starter and ignition wires. If the control module is placed just behind the
driver's side dash it can easily be disconnected.
When locating the control module, try to find a secure location that will not require
you to extend the harnesses’ wires (they are 1.5 meters long). Keep it away from the
heater core (or any other heat sources) and any obvious leaks.
Some good control module locations: Above the glove box, inside the center console,
above the underdash fuse box, above the radio, etc.

integrated LED/Valet®switch
Things to remember when positioning the integrated LED/Valet®switch:
• It should be visible from both sides and the
rear of the vehicle, if possible.
• It needs at least 1-1/2" clearance to the rear.
• It is easiest to use a small removable panel,
such as a switch blank or a dash bezel.
Remove it before drilling your 5/16" hole.
starter kill relay
If the Starter Kill Relay or it’s connections are immediately visible upon removal of the
underdash panel, they can easily be bypassed. Always make the relay and its con-
nections difficult to discern from the factory wiring! Exposed yellow butt connectors do
not look like factory parts, and will not fool anyone! For this reason, routing the starter
kill wires away from the steering column is recommended.
connecting your wires
Now that you have decided where each component will be located, you’re going to
find the wires in the car that the security system will be connected to.
IIMMPPOORRTTAANNTT!!Do not use a 12V test light to find these wires! All testing described in
this manual is described using a digital multimeter.
obtaining constant 12V
We recommend two possible sources for 12V constant: The (+) terminal of the battery,
or the constant supply to the ignition switch. Always install a fuse within 12 inches
of this connection.

IIMMPPOORRTTAANNTT!!Do not remove the fuse holder on the red (H1/11) wire. It ensures that
the control module has it’s own fuse, of the proper value, regardless of how many
accessories are added to the main power feed.
finding the 12V switched ignition wire
The ignition wire is powered when the key is in the run or start position. This is
because the ignition wire powers the ignition system (spark plugs, coil) as well as the
fuel delivery system (fuel pump, fuel injection computer). Accessory wires, on the other
hand, lose power when the key is in the start position to make more current available
to the starter motor. Use the following procedure to find (+)12V with your multimeter.
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the ignition wire.
The steering column harness or ignition switch harness is
an excellent place to find this wire.
4. Turn the ignition key switch to the run position. If your
meter reads (+)12V, go to the next step. If it doesn’t, probe
another wire.
5. Now turn the key to the start position. The meter dis-
play should stay steady, not dropping by more than a few
tenths of a volt. If it drops close to or all the way to zero,
go back to step 3. If it stays steady at (+)12V, you have
found an ignition wire.

finding a parking light wire
The parking light wire is often found near the switch. Many cars have the switch built
into the turn signal lever, and in these cars the parking light wire can be found in the
steering column. The same wire is often available in the kick panel or running board.
(+) parking light wire
Use the following procedure to find (+) parking light wire with your multimeter.
1. Set to DCV or DC voltage (12V or 20V
is fine).
2. Attach the (-) probe of the meter to
chassis ground.
3. Probe the wire you suspect of being the
parking light wire. Usually, the area
near the headlight/parking light switch
is an excellent area to start, as is the
kick panel.
4. Turn on the parking lights. If your meter shows (+)12V, turn off the parking lights
and make sure it goes back to zero.
5. If it does return to zero, turn the parking lights back on and, using the dash light
dimmer control, turn the brightness of the dash lights up and down. If the meter
changes more than a volt when using the dimmer, look for another wire. If it
stays relatively close to (+)12V, you have found your parking light wire.
(-) parking light wire
Use the following procedure to find (-) parking light wire with your multimeter.
1. Set to DCV or DC voltage (12V or 20V
is fine).
2. Attach the (+) probe of the meter to
+12V.
3. Probe the wire you suspect of being the
parking light wire. Usually, the area
near the headlight/parking light switch
is an excellent area to start, as is the
kick panel.
