IIMMPPOORRTTAANNTT!!This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to its intended use.
■Please read this entire installation guide before beginning the installation. The installation of this remote start
system requires interfacing with many of the vehicle’s systems. Many new vehicles use low-voltage or multi-
plexed systems that can be damaged by low resistance testing devices, such as test lights and logic probes
(computer safe test lights). Test all circuits with a high quality digital multi-meter before making connections.
■Do not disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air bag, avoid
disconnecting the battery if possible. Many airbag systems will display a diagnostic code through their
warning lights after they lose power. Disconnecting the battery requires this code to be erased, which can
require a trip to the dealer.
■Check with the customer on status LED location.
■Remove the domelight fuse. This prevents accidentally draining the battery.
■Roll down a window to avoid being locked out of the car.
■Test all functions. The “Using Your System” section of the Owner's Guide is very helpful when testing.
■When testing, don’t forget that this system is equipped with Nuisance Prevention Circuitry (NPC®). NPC® can
bypass trigger zones, making them appear to stop working. See the
Nuisance Prevention Circuitry section.
■Review and complete the
Safety Check section of this guide prior to the vehicle reassembly.

■Keep it away from heat sources, such as radiators, exhaust manifolds, turbochargers, and heat shields.
■Mount it where a thief cannot easily disconnect it, whether the hood is open or shut. Both the siren and its
wires should be difficult to find. This usually involves disguising the wire to look like a factory harness.
■We recommend against grounding the siren to its mounting screws. Instead, we recommend running both the
red and black wires into the passenger compartment and grounding to one common point for all devices. After
all, both wires are the same length and come already bonded together. Whenever possible, conceal your wires
in the factory harnesses or in the same style loom as the factory.
■When possible, place the siren on the same side of the vehicle as the control module, where its wires will
reach the control module’s wires without extending them. Always run the wires through the center of a
grommet, never through bare metal!
■Point the siren down so water does not collect in it.

■Never put the control module in the engine compartment!
■The first step in hot-wiring a vehicle is removing the driver's side under-dash 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 mounting the control module, try to find a secure location that will not require you to extend the har-
nesses’ wires (they are 1.5 meters long). Keep it away from the heater core (or any other heat sources) and
any obvious leaks.

■The higher the control module is in the vehicle, the better the transmitter range will be. If you put the control
module under a seat or inside a metal dashboard, range will diminish.
Some good control module locations: above the glove box, inside the center console, above the under-dash fuse
box, above the radio, etc.

■Find a spot close to the control module so that the wires do not need to be extended. Keep it away from the
heater core (or any other heat sources) and any obvious leaks.

■Using double-sided tape or hook-and-loop fastener to mount to a trim panel or an air duct,
or
■Wire-tying to a wire harness.
If mounting the sensor where it cannot be easily reached for adjustment, hook-and-loop fastening tape (such as
Velcro) is recommended for ease of removal for future adjustments.
NNOOTTEE::In many vehicles, tying the sensor to a steering column or screwing it to metal will result
in poor sensitivity, especially at the rear of the vehicle.

IIMMPPOORRTTAANNTT!!When the vehicle is delivered, please show the user where this switch is located
and how to disarm the system with it.
Ensure that the location you pick for the switch has sufficient clearance to the rear. The switch should be well
hidden. It should be placed so passengers or stored items (such as in a glove box or center console) cannot acci-
dentally hit it. The switch fits into a 9/32-inch hole.
This system has Remote Valet. The user can enter and exit Valet® Mode without having to reach the
Valet/Program switch. This feature was introduced so that switch location was less critical in day-to-day use. As
long as the Valet/Program switch can be reached to disarm without a transmitter, easy access is not important.

■It should be visible from both sides and the rear of the vehicle, if possible.
■It needs at least 1/2-inch clearance to the rear.
■It is easiest to remove a small panel, such as a switch blank or a dash bezel, before drilling a 9/32-inch hole.
■Use quick-disconnects near the LED wires if the panel is removable. This lets mechanics or other installers
remove the panel without cutting the wires.

If optional starter kill relay or its connections are immediately visible upon removal of the under-dash panel,
they can easily be bypassed. Always make the relay and its connections 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 optional starter kill wires away from the steering column is recommended.
The relay satellite wiring carries large amounts of current. The wires should not be extended and should be cut
to the minimum length necessary. Since the relay satellite is functioning as the ignition switch in the vehicle,
it is often convenient to mount the relay satellite close to the main ignition switch harness.

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 or logic probe (computer safe test light) to find these
wires! Use a digital multimeter for all testing.
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. If the fuse also will be powering
other circuits, such as door locks, a power window module, a Nite-Lite® headlight control system, etc., fuse
accordingly.
IIMMPPOORRTTAANNTT!!Do not remove the fuse holder on the red wire. It ensures that the control module
has its own fuse, of the proper value, regardless of how many accessories are added to the main
power feed.

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 lose power when the key is in the start position to make more current available to the starter motor.
HHoowwttooffiinndd((++))1122VViiggnniittiioonnwwiitthhyyoouurrmmuullttiimmeetteerr::
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 excel-
lent 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 display 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.
The starter wire provides 12V directly to the starter or to a relay controlling the starter. In some vehicles, it is
necessary to power a cold start circuit. A cold start circuit will test exactly like a starter circuit, but it does not
control the starter. Instead, the cold start circuit is used to prime the fuel injection system for starting when the
vehicle is cold.

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 starter wire. The steering
column is an excellent place to find this wire. Remember you do not
need to interrupt the starter at the same point you test it. Hiding
your optional starter kill relay and connections is always recommended.
4. Turn the ignition key switch to the start position. Make sure the car
is not in gear! If your meter reads (+)12V, go to the next step. If it doesn’t, probe another wire.
5. Cut the wire you suspect of being the starter wire.
6. Attempt to start the car. If the starter engages, reconnect it and go back to Step 3. If the starter does not
turn over, you have the right wire.
