Installation Order of Each Component
Please familiarize yourself with all components before installation. In addition,
it is suggested (depending on the vehicle) the 3-port interface “hub” be installed
first (under the vehicle’s dash) and wire it to a 12-volt switched circuit. Before
installing the other components, plug each component into the appropriate outlet
in the 3-hole interface “hub” to confirm LaserPro™ 904 is functioning properly.

Since Laser signals do not pass through objects, including plastic, it is important
that the front transceivers be mounted with a clear, unobstructed view of the road
ahead, and completely level.

Under Dash Mounting
To mount the control display under the dash
using the supplied under-dash bracket, drill
two holes (#35, .110 diameter) to fasten the
control display bracket with the two (2) black
3/8” self threading screws provided. Once
installed, the control panel can slide into the
bracket using the slots on each side of the
unit.

display exposed.
Finally, connect each jack from each
transceiver to the “Y” connector provided.
NOTE: For in-dash mounting, do not install
the control display into the dash until the
front laser tranceivers and interface “hub”
have been installed, and the cables have been
routed through the in-dash mount.

"Y" CONNECTOR
With a mounting location selected, plug the
“pin” connectors to the back of the control
display and the opposite end into the
appropriate 3-port interface “hub”.

In-Dash Mounting
The contol display can be mounted directly

*First, peel the back off the template provided
and place over the selected area.
*Drill two 3/16” diameter holes as indicated
on the template and a third hole in the center
of the cutout area to allow a saw blade to
enter. Cut along the template outline.
*Once the portion of the dash has been cut
away, remove the template and insert the
dash mount frame into the area and fasten to
the dashboard using two (2) 3/4” black oval
head screws with flat washers, lock washers
and nuts on back side. Special notches allow
the control display to be mounted into the

2. Front Laser Transceivers
a) Postion each of the two front Laser
transceivers on either side of the front license
plate. Many vehicles have open areas in the
polyurethane bumpers in or around this area.
If possible, choose an area between the
license plate and the center point of headlight
lens – see diagram (2)
b) Using the mounting brackets supplied,
mark the location and drill pilot holes if
necessary.
c) Mount the transceivers using the supplied
hardware. NOTE: Both of the front
transceivers must be level to the road. Use
the supplied spirit level to ensure each
transceiver is level to within +/- 5%. Align the
spirit level along the etched line which
appears at the side of each transceiver.
a) Remove the license plate screws from the
license plate.
b) Align the two holes in the rear Laser
transceiver to the license plate; use supplied
screws to re-attach.
c) Route the wire emanating from the
transceiver through the trunk compartment
and into the vehicle’s interior and up to the
3-hole interface “hub”. Cable can also be
routed under the vehicle, provided it is kept
away from heat and moving parts.
d) Insert the jack into the hole labeled “Rear
Laser”.
NOTE: Ensure you do not block any
information on the license plate. The cable
may be cut if too long, however, it must be
reconnected using solder for each of the three
wires and sealed with heat-shrink tubing.
4. Routing of Front Laser
Transceiver Cables
a) Route the cable from the two front Laser
transceivers to the vehicle’s firewall, and
secure with supplied tie-wraps.
b) If a suitable opening in the firewall does
not exist, drill a 13/32” or 7/16” hole to insert
the cable.
c) Pull the cable through the firewall, and
plug into the jack marked Front Laser.
d) Pull the grommet through the firewall to
seal the hole. If necessary, use silicon sealant
(not supplied).
Note: Do not splice the cable. Ensure
cable is kept away from any hot or moving
parts.
5. 3-Port Interface “hub”
a) Install the 3-hole interface under the
vehicle’s dash using the supplied tie-wraps.

b) Connect black wire (-) to a ground source
such as the vehicle’s floor pan. Connect the
red striped wire (+) to a switched 12-volt
supply. Use the blue colored wire connector
to tap into an existing circuit, if needed.
Note: If LaserPro™ 904 is left in the “on”
position, it will automatically power on and
off with ignition.
Testing Procedure
After all components are installed
correctly, turn LaserPro™ 904 ON by pressing
the Power On button and turn the vehicle’s
ignition to the “on” position; LaserPro 904 will
cycle through its startup test sequence.

• DO NOT drill holes into the front
Laser transceivers.
1. Control Display
• Make certain the area selected is
suitable before drilling holes into
the bumper.
a) Determine an appropriate location to
mount the control display based on visibility
and customer input.
• Keep cables away from moving
parts or hot or heated surfaces.
b) Install the display using the hook and loop
fastener.
c) Plug the “pin” connectors to the back of
the control display and the opposite end into
the appropriate 3-port interface “hub”.
