installation points to remember
Before beginning the installation:
■Check with the customer on Status LED location.
■Use seat and fender covers to protect the vehicle.
■Remove the domelight fuse. This prevents accidentally draining the battery.
■Roll down a window to avoid being locked out of the car.
■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.
■Remove necessary under-dash trim panels to provide access for mounting the system’s components.
IMPORTANT! Please read this entire installation guide before beginning the installation. The instal-
lation of this security system requires interfacing with many of the vehicle’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.
IMPORTANT! Many airbag systems will display a diagnostic code through their warning light after
they lose power. Disconnecting the battery requires this code to be erased, which can require a trip
to the dealer.
After the install:
■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 circuitry to prevent false alarms. This circuitry
can bypass both instant trigger zones, making them seem to stop working.
■Carefully reassemble the under-dash trim panels.
■Inspect 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 system in most vehicles. Some
vehicles may require additional tools.
■Digital multi-meter
■Torx driver set
■Nutdriver and/or socket set
■Panel removal tool
■Drill bit set
■Phillips head screwdriver
■Work light

deciding on component locations
Some things to remember about mounting the siren:
■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.
Some things to remember about where to mount the 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 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 suffer.
Some good control module locations: above the glove box, inside the center console, above the under-dash fuse
box, above the radio, etc.
IMPORTANT! 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.

NVSL4000 7 - English
Things to remember when positioning the Status LED:
■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 use a small removable panel, such as a switch blank or a
dash bezel. Remove it before drilling your 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.
finding the wires you need
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.
IMPORTANT! 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 headlight control system, etc., fuse accordingly.
IMPORTANT! 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.
How to find (+)12V ignition 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 steer-
ing column harness and ignition switch harness are excellent
places 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 best places to find the door switch wire are:
■At the pin switch: When testing at the pin switch, check the wire to ensure that it “sees” all the doors. Often,
the passenger switch will cover all the doors even if the driver’s switch will not.
■In some GM vehicles with isolated door pins, the door pin wires may be located at the body control module.
■At the dome light: This may not be your best choice if the vehicle has delayed domelight supervision.
Once you have determined the wire color, the easiest place to connect to the wire is often at the kick panel, at
the windshield pillar, or in the running board. When an easy location is not available, running a wire to the dome-
light itself is often the best solution.
How to find a door pin switch trigger wire with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. In most Fords, fasten the (-) probe of the meter to chassis ground. In most other cars, fasten the (+) probe
of your meter to (+)12V constant.
3. Probe the wire you suspect of being the door trigger wire. If the meter reads (+)12V when any door is opened,
you have found a trigger 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 avail-
able in the kick panel or running board.
How to find a (+) parking light flash 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.
making your wiring connections
Before making your connections, plan how your wires will be routed through the vehicle. For instance, the yellow
ignition input, the red 12V constant input, and the orange ground-when-armed output will often be routed
together to the ignition switch harness. In order to keep the wiring neat and make it harder to find, you may
wish to wrap these wires together in electrical tape or conceal them in tubing similar to what the manufacturer
used.
There are two acceptable ways of making a wire connection - solder connections and crimp connectors. When
properly performed, either type of connection is reliable and trouble-free. Regardless of whether you solder your
connections or you use mechanical-type crimp-on connections, ensure that all connections are mechanically
sound and that they are insulated.
Cheap electrical tape, especially when poorly applied, is not a reliable insulator. It often falls off in hot weather.
Use good quality electrical tape or heat shrink.
■Never twist-and-tape the wires together without soldering.
■Never use “fuse taps”, as they can damage fuse box terminals.
If you use tapping connectors such as 3M T-Taps (not to be confused with Scotch-Locks), avoid using them in
higher-current applications (constant 12V, ground, etc.). Some tapping connectors are inferior in quality and
should be avoided.
