1.
Turn the ignition on and press the brake pedal to make sure the brake light
illuminates.
2.
Connect the black lead of the voltmeter to ground and set the dial to DC volts.
3.
Probe the wires at the brake light switch with the voltmeter. The voltmeter should
read +12V when you press the brake pedal; 0 volts when released.
4.
Connect the BLUE/WHITE wire to the brake wire.
siren
Mount the siren in the engine compartment away from moving or heat-producing
components. Mount the siren in the engine compartment on the opposite side from the
exhaust manifold. The siren must not be accessible or visible from outside or under the
vehicle. Point the siren downward to avoid water collection and enhance sound pro-
jection.
1.
Mount the siren using all three sheet metal screws supplied.
2.
Connect the siren's BLACK wire to the control unit's YELLOW wire.
3.
Connect the siren's RED wire to the control unit's RED wire.
horn connection (option)
If you choose not to use the standard siren, the yellow wire can be programmed as a
horn output (refer to Features Programming in this manual) and can be connected to
the vehicle's horn. This output is negative and can provide up to 2 amps.
tachometer connection
Some newer vehicles do not have a conventional ignition coil marked (+) and (-). In
these instances, you will need to locate the tach wire:
1.
Try to locate the distributor cap which all spark plug wires run into. There should
be the same number of plug wires as the number of cylinders. If there is an extra
plug wire, the vehicle has a separate coil.
2.
Follow the extra plug wire to the coil module, which will have two or more wires.
a.
If there are only two wires: one is the ignition, the other wire is the negative
coil wire. Connect the Black/Gray wire from the control module to the
negative coil wire.
