Controller
1
Determine the best location for the Display
Controller in the vehicle’s interior. (Consult
customer if necessary.)
2
Install Controller using supplied double-
sided tape located on the back. Simply peal
off the paper backing and press onto clean
surface.
3
Route cable and plug into jack marked
“Controller” on the Interface.
Note:
Make certain that the Controller can be
easily accessed without interfering with
normal driving.
Radar/Laser Receiver Cable
5
Pull grommet (located on the receiver
cable itself) through the firewall to seal the
hole. Use silicone sealant (not supplied) if
necessary.
Note:
1. Connection between the Receiver and the
receiver cable, must be located in a dry
location under the hood.
2. Only drill hole in firewall after thoroughly
investigating location first, ensuring no
other wires, hoses, etc. will be damaged.
3. Keep all cables away from moving parts,
and hot surfaces (radiator, hoses, etc.).
4. DO NOT splice cable.
1
Connect the receiver cable to the Receiver.
2
Route cable to firewall, and secure with
zip-ties (included).
3
Route receiver cable into the vehicle’s
interior. If there is not a suitable opening,
drill a 13/32" or 7/16" hole.
4
Pull cable through firewall, and plug
connector into the jack labeled “Front
Receiver” on the Interface.
Radar/Laser Receiver
1
Determine the best location for the
Receiver. The best location is typically
under the bumper, or inside the front grill of
the vehicle. For the best performance, install
the Receiver horizontally, with a clear “view”
of the road.
2
Using the supplied mounting hardware,
mark the hole locations and drill pilot holes
in the vehicle if necessary. It’s best to check
and double-check clearances BEFORE
drilling the holes.
3
Mount the Receiver using the supplied
hardware. (If right-angle mounting bracket
is used, secure Receiver to the right-angle
bracket first, then install bracket with
Receiver to the vehicle.)
Note:
1. Do not drill holes in the Receiver itself.
2. Thoroughly investigate location before
drilling any holes.
3. Keep all cables away from moving parts,
and hot surfaces (radiator, hoses, etc.).
4. DO NOT splice cable.

Display
1
Determine the best location for the Display
in the vehicle’s interior. (Consult customer if
necessary.)
2
Install Display using double-sided tape on
the back. Simply remove paper backing and
press onto clean surface. You may also
custom-install the display into the dashboard
using the supplied template. Seek
professional assistance for this.

Route cable and plug into jack marked
“Display” on Interface.
Note:
Make certain that the Display is clearly
visible from the driver’s position.

Optional Concealed Display
1
Drill a 1/4" hole, and install the LED clip.
2
Snap LED into clip from behind.
3
Plug the modular connector into STi-R’s
Interface marked “Concealed LED Display.”
Amplified Speaker
1
Determine the best location for the
Speaker in the vehicle’s interior. (Consult
customer if necessary.)
Note:
The speaker is loud enough to be mounted
under the dash so it is not seen.
2
Mount the Speaker bracket using the
supplies hardware.
Interface
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 STi-R 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
The front Receiver, Display and Controller
all plug into the Interface. (Be sure to plug
all cables into the correct labeled jacks.)
C
TEST
After all components are installed correctly:
1
Turn vehicle’s ignition to the “on” position.
2
Turn the STi-R on by pressing the “PWR”
button on the Controller.
3
The STi-R will cycle through a startup
sequence.
4
If any error messages come up, see page 23
of the Owner’s Manual for details.
3
Plug the audio line (ear phone jack
connector) into the Interface jack marked
