SF-Series Installation Procedures
Pre-Installation Vehicle Check
Before beginning the installation, turn the vehicle on. Verify that no Check Engine lights, error codes, or
warnings appear on the gauge console, dashboard, or vehicle display. It may be necessary to cycle
through displayed messages or screens to verify. If any Check Engine lights, error codes, or warnings
appear, report these to the site contact before proceeding.
For installations with OBD-II network connections: The SF-Series device cannot be connected to the OBD-
II network if another 3rd-party device is also connected to the same network. To proceed with the
installation, verify that no other 3rd-party devices are connected to the OBD-II diagnostic port.
Mount the Bracket and Event Recorder
WARNING: Before mounting the bracket and event recorder, consult the vehicle manufacturer's
recommendations and any applicable federal, state, provincial and local laws that restrict mounting devices
on a vehicle’s windshield or other locations in a vehicle.
Mounting Preparation
CAUTION: An improperly positioned event recorder can reduce program effectiveness.
The event recorder should be mounted in a location that
provides an unobstructed view of the driver and the
road in front of the vehicle.
1. Interior-Facing Lens View: Should span from the
outside shoulder of the driver to the outside
shoulder of a front seat passenger. If possible, it
should show the lap band of the seatbelt.
2. Exterior-Facing Lens View
a. Should be inside the path of the wiper
blades.
b. Should capture a clear view of everything in
front of the vehicle, beginning as close to
the front of the vehicle as possible without
cutting off the horizon.
To temporarily gauge the best position, first loosen the
Torx screws so the event recorder can rotate in the bracket. Then hold it up to the windshield.
If windshield mounting is not possible/permitted in the vehicle or jurisdiction, alternative mounting
methods are available under Installation of Optional Parts.

(North America Edition)
Mounting Location Recommendations and Restrictions
WARNING: Some countries/regions have adopted laws that restrict locations where objects can be attached
to the vehicle windshield. Always refer to any applicable federal, state, provincial and local laws that
concern mounting devices on vehicle windshields or other locations in a vehicle before choosing a
mounting location.
For those vehicles that are subject to U.S. Department of Transportation, Federal Motor Carrier
Safety Administration (FMCSA) regulation, the following figures provide guidelines for mounting the
Lytx event recorder on the vehicle windshield that work within regulations set by the FMCSA*.

©2022 Lytx, Inc. - Confidential & Proprietary. Page 15 of 45
(North America Edition)
CAUTION: To mount the device, the air temperature must be at least 50°F (10°C). The ideal temperature
range is 70-100°F (21-38°C).
CAUTION: Do not use a heat torch to heat up the windshield or adhesive on the bracket as this may reduce
bracket adherence. If additional heat is required, use the vehicle heating system for the windshield.
CAUTION: Steps 1-3, cleaning the area and drying it, are critical to prevent the bracket from falling off later.
CAUTION: Do not peel the backing from the bracket's adhesive in this section.
1. Apply isopropyl alcohol on the windshield mounting area and dry it off with a clean cloth, removing
any debris. This is the area behind the rear view mirror on the passenger side or the equivalent
area if there is no rear view mirror (see below).
2. Clean the mounting area again with the Lytx-
supplied alcohol wipe.
3. Wait 2 minutes for the mounting area to air dry
before applying the device bracket. Do not dry
it with a cloth.
4. Following the mounting location guidelines
above, hold the assembly in place and trace
the outline of the bracket on the windshield
with a marker. Make sure the traced guide
marks are level.
5. Remove the event recorder from the mounting
bracket.
6. Check the fit of the bracket against the windshield. If the windshield is curved, you may gently
bend the bracket so it lies flush against the glass.
Best practice: Select a surface location with minimal curvature.
7. Check again to make sure you’ve selected the best mounting location.
a. Sit in the driver’s seat while holding the device up. Make sure it doesn’t block the driver’s
view of the road.
b. Turn on the wipers and rotate mirrors, sun visors, and other objects near the device to make
sure they cannot block either lens.

(North America Edition)
Attach the Bracket and Event Recorder
CAUTION: The adhesive is very sticky. Once applied, it will not easily come off. Take care to attach the
bracket to the mounting location properly.
CAUTION: Do not apply excessive pressure as it may cause the windshield to break.
CAUTION: After removing the backing from the bracket's adhesive, apply the bracket to the windshield
immediately. If you leave the adhesive exposed for too long, it may be compromised.
1. Remove the backing from the adhesive side of the
bracket. Carefully attach the bracket to the
windshield.
a. The bracket has slightly longer and shorter legs.
Orient the bracket so the shorter legs are facing
down.
b. Place the left edge of the bracket against the
windshield, aligned with the marks, and make
sure it is level.
c. Press the bracket firmly against the windshield
starting at the left and pressing downward to the
right.
2. Check from outside the vehicle for large air bubbles
under the bracket. If you find any:
a. Apply additional pressure to the bracket.
b. Slide a pin between the bracket and windshield to let out the air.
3. Wait 10 minutes to allow the bracket's adhesive to bond.
4. Place the event recorder in the bracket.
5. Adjust the event recorder so it hangs vertically (plumb).
See Figure C.
6. Secure the event recorder in the bracket using the two T-
27 Torx screws.

(North America Edition)
Connect Electrical Wiring
WARNING: Only approved wire connection methods are recommended. Refer to the vehicle
manufacturer’s service manual to determine if soldering, sealing crimp connections, Add-A-Circuit, Posi-
Tap, sealing butt connections, or OEM connections to open connection ports are approved. Never use plier
tap products such as insulation displacement connectors (i.e. ScotchLoc connectors) when installing the
SF-Series device(s).
WARNING: Never wire the SF-Series device(s) in a manner that shares a connection with another
aftermarket product in the vehicle. Independent connections should always be used.
WARNING: All wires that carry electrical current to the SF-Series device(s) must be fused. Failure to
fuse the power, ground, and ignition wires can lead to serious personal injury and/or property damage.
If any wires or cables containing fuses/fuse boxes need to be cut or otherwise shortened, always be
certain to replace such fuses/fuse boxes or install new ones.
WARNING: Wire Protection: Take all necessary measures to protect all wire runs through a metal surface
with a grommet or other device and all wire runs outside the vehicle cab with a loom. Always protect
against wire fatigue and harness abrasion by properly attaching wires at closely spaced intervals, while
avoiding contact with sharp edges or doing anything else that might result in exposed wires. All wires
should be secured with tie wraps at least every one foot (30 cm/300 mm) or less. Do not over-tighten any
tie wraps.
WARNING: Cable Routing: Make certain that neither the cable nor your installation activities interferes
with any airbag-related mechanisms or otherwise risks affecting airbag deployment. Consult the
vehicle manufacturer for the location of any airbag sensors and systems and restrictions that may apply.
