Step One:
Deciding on component locations.
Siren
Some things to remember about where to mount the siren:
1. Keep it away from heat sources. Radiators, exhaust manifolds, turbochargers, and heat shields are all
things to avoid.
2. 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.
3. 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.
4. When possible, put 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!
5. Point the siren down so water does not collect in it.
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 igni-
tion 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.
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, and you
may wish to add a 542H Range Extending Antenna (available
separately).
Some good control module locations: above the glove box,
inside the center console, above the underdash fuse box,
above the radio, etc.
