IMPORTANT - PLEASE READ BEFORE INSTALLING
When installing the Laser DefuserPlus outside of the system’s license plate frame, the unit should be mounted as
close to the center of the vehicle as possible, without obstruction. The mounting location of the Laser DefuserPlus
is important, as police laser gun operators are trained to aim for the flat, reflective surface of a targeted vehicle’s
front license plate. In states that do not require a front license plate, operators will traditionally aim for the front,
center of the vehicle. This procedure allows the operator to effectively "bounce" the laser signal back to the gun
to calculate the vehicle’s speed.

1. For best visibility, choose a mounting location for the laser L.E.D.
as close to the vehicle gauges as possible. See diagram A1.
2. Check for proper clearance behind the area where the L.E.D.
will be installed (approximately 1”), and drill a 3/16” hole in the
chosen location. See diagram A2.
3. Route the L.E.D. wires under the dash per diagram A3 and
connect according to the appropriate block diagram.

cover from the license plate. Remove license plate.
See diagram C1.

Note: When integrating the Laser DefuserPlus with the K40 remote radar system, the Laser DefuserPlus
will utilize the same warning light/speaker(s) as the K40 remote. Therefore, you will not
need to install the red L.E.D. alert light or piezo beeper that come with the Laser DefuserPlus.

1. For maximum audio output and concealment, mount the
piezo beeper in the driver’s left air vent. See diagram B1.
2. Use the supplied double stick “O” ring tape
to mount the piezo beeper.
3. Route the piezo beeper wires through or under the dash
per diagram B1 and connect according to the appropriate
block diagram.

2. Position the Laser DefuserPlus around the existing front license
plate and mount it against the factory license plate bracket.
Use the existing mounting bolts or K40 nylon bolts to secure the
DefuserPlus frame and license plate to the bracket.
See diagram C2.
3. Route the black and clear zip cord wires into the engine compartment either through the grill or under the
bumper. See diagram C3.
4. Pass both the black and clear zip cord wires towards the vehicle’s firewall and through an existing rubber
grommet into the vehicle’s interior. See diagram C4.
5. Connect wires according to the appropriate block diagram and insert the 3 amp fuse into the fuse holder.
Secure the watertight fuse cover. Turn on the ignition key to verify operation.
Caution:
Avoid hot or moving parts.
Note: For optimum per-
formance, the DefuserPlus
must be mounted parallel to
the ground. Use the supplied K40
nylon nuts and bolts to correct the
mounting angle of the DefuserPlus
either up or down as needed.
On some vehicles, it may be necessary
to adjust or reposition the factory
license plate bracket to achieve the
parallel mounting.
On vehicles that have only one set of
bracket mounting holes, it is recommended that the Laser DefuserPlus
and the license plate be bolted
together to eliminate any vibration.

1. Choose a mounting location inside the lower air intake vent or
grill that has a clear, unobstructed view of the road.
2. Separate the Laser DefuserPlus module from the license plate
frame by removing the two screws on the backside of the
frame. See diagram D1.
