11.
Mount the siren.
The siren must be mounted securely under the hood. Mount the siren where the siren
cannot be seen or reached from below the vehicle. Mount it away from any heat sources or moving parts
Point the siren down to avoid water collecting in it.
12.
Make your connections under the hood
. For most alarm and remote start installations you will need to
locate and connect to the vehicle’s tachometer wire and hood pin wire under the hood. Most remote start
systems have a hood trigger input to shut down or disable the remote start when the hood is opened. This
is a safety feature. For a security system, the hood trigger input will trigger the alarm if the hood is
opened. The intent of a hood trigger input is to protect the engine compartment and the contents that are
susceptible to tampering such as the siren, battery, or starter. Generally, models equipped with a factory
security system have a factory hood pin switch. Some vehicles do not have a factory hood pin. In order
to protect the engine compartment a hood pin must be added. Some systems include a pin switch and pin
switch bracket that can be used as a hood pin, or they are available at most car audio and electronics
stores. The pin switch bracket is used to mount the hood pin switch. The bracket is typically and “L”
shape and is mounted to the side of the firewall or inside fender area.
13.
Make your connections inside the driver’s door
. This will not be necessary on most vehicles, but a
handful of vehicles will require making connections inside one or more of the doors of the vehicle. This
may be required if the door lock wires, door trigger wire, or factory alarm arm or disarm wires are located
only inside one or more of the doors of the vehicle.
14.
Make your connections in the driver’s kick panel.
This is the area under the driver’s side dash on the
far left side. On many vehicles the door lock wires, door trigger wire, parking light wire, brake wire, factory
alarm disarm wire and/or trunk trigger wire can be found in the driver’s kick panel. These wires may be
found at a module up high in the driver’s kick panel or in the corner against the firewall or they may be
found low in the drivers kick panel in a harness leading towards the rear of the vehicle.
15.
Make your connections in the passenger kick panel or behind the glove box.
It will not be necessary
to make connections in this location in many vehicles, but on some vehicles wires must be located in a
harness or at a module in the passenger kick panel or behind the glove box.
16.
Make your connections in the trunk or rear hatch.
It will not be necessary to make connections in this
location on most vehicles, but on a few vehicles the trunk trigger wire or trunk release wire can only be
found in the trunk area.
17.
Make your connections at the steering column.
This is where you will make all your power
connections and in some cases the horn trigger wire. Take care in working with the ignition harness of
any vehicle. Many other wires, including airbag wires, can usually be found in the ignition harness of most
vehicles. You want to be careful not to accidentally unplug or damage any of the connectors or the wiring.
Unplugging any of the connectors may deploy the airbags or trigger a “check engine” light or similar error
code light to appear on the dash.
18.
Connect chassis ground.
This is one of the most important connections. A poor or improper ground
causes 90% of all problems that may arise with an alarm or remote start. The best ground point in a
vehicle is a place with a good physical connection to the same metal that the vehicle battery ground itself
shares. Avoid using the bracing underneath the dash. This is a high-resistance ground point and should
not be used. It is preferred that a factory ground point (usually located in the driver’s kick panel) is used.
Some manufacturers in their installation manual recommend and insist on using the negative terminal of
the battery for the alarm or remote start system’s ground point. Connect this wire to bare metal, preferably
with a factory bolt rather than your own screw. Screws tend to either strip or loosen with time. Ground all
components to the same point. If a screw must be used, connect chassis ground to bare metal and use a
star washer to ensure a proper ground connection. Check for clearance on both sides before drilling
