1
Determine the best location for the
Display Controller in the vehicle’s
interior. (Consult customer if
necessary.)
2
Install Display Controller using
supplied velcro, or double-sided tape.
3
Route cable and plug into jack
marked “Display” on Interface.
Note:
1. Make certain that the Display is
clearly visible from the driver’s
position, and that the controls can be
easily accessed without
interfering with normal driving.

1
Remove two license plate screws
(top or bottom).
2
Mount Laser SHIFTER to plate using
supplied mounting bracket.
3
Route wire through trunk
compartment, and into the vehicle’s
interior.
4
Insert connector to jack labeled
“Rear Shifter” on Interface.
Tips
1. Do not block license plate
illumination.
2. Do not cover any required license
plate information.
Installation Alternatives:
1. Cable can be routed under vehicle
(keep away from hot and moving
parts) then brought into the vehicle’s
interior.
2. DO NOT SPLICE CABLE unless
within interior of vehicle. Reconnect
and solder each of the three wires,
and seal with heat-shrink tubing.
1
Determine best location for the
Laser SHIFTERS. For optimum
performance, install each laser
SHIFTER on either side of the front
license plate, with a clear “view” of
the road. If possible, center each
SHIFTER module between the license
plate, and the outside edge of the
vehicle. (See photo below at left.)
2
Determine which mounting
hardware (metal U-bracket or grill
clamp) is best suited to the vehicle.
Mount the front SHIFTERS to a sturdy
part of the grill or bumper. To tighten
the grill clamp, simply insert a 9/64
Allen wrench into the front slot of the
clamp. (See illustration below.)
3
Before tightening, pull SHIFTER
cables through grill area and make

1
Install Interface under the dash
using supplied zip-ties. DO NOT
MOUNT IN ENGINE COMPARTMENT.
2
Connect black wire (–) to ground,
and red-striped wire (+) to a switched
12-volt supply. (If the Laser SHIFTER
is left in the “on” position, it will
automatically power on and off with
the ignition.) Use blue 3M connector
(provided) to tap into existing circuit
if needed.
3
Be sure to plug all cables into the
correct labeled jacks.
1
Determine best location for the
Remote Mute Button.
2
Clean surface area.
3
Remove paper backing on the back
of the button, and press onto surface.
4
Route cable and plug into jack
marked “Mute” on Interface.
1
Route Laser SHIFTER cables to
firewall, and secure with zip-ties
(included).
2
Route both SHIFTER cables into the
vehicle’s interior. If there is not a
suitable opening, drill a 13/32" or
7/16" hole.
3
Pull cables through firewall, and
plug into jacks marked Front Shifter 1
and Front Shifter 2 on interface.
4
Pull grommet (located on each
cable) through the firewall to seal the
hole. Use silicone sealant (not
supplied) if necessary.
Note:
1. Only drill hole in firewall after
thoroughly investigating location first,
ensuring no other wires, hoses, etc.
will be damaged.
2. Keep all cables away from moving
parts, and hot surfaces. (Radiator,
hoses, etc.)
3. DO NOT SPLICE CABLE unless
within interior of vehicle. Reconnect
and solder each of the three wires,
and seal with heat-shrink tubing.
certain that both SHIFTERS (front
lens) are level to the road. THEY
MUST BE LEVEL TO WORK PROPERLY.
Note:
1. Thoroughly investigate location of
SHIFTERS and cables before installing.
2. Keep cables completely away from
all moving parts and hot surfaces in
the engine compartment.
3. DO NOT SPLICE CABLE unless
within interior of vehicle.
4. Double-check to make certain the
SHIFTERS are level and have a clear
view of the road.
