Mounting Location Guidelines
CAUTION: An improperly positioned event recorder can reduce program effectiveness.
The event recorder needs to 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: Must span from the outside shoulder of the driver to the
outside shoulder of a front seat passenger.
2. Exterior-facing Lens View
a. Must be inside the path of the wiper blades.
b. Must 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 use the ER device to temporarily gauge the best position, first loosen the Torx screws so
the ER can rotate in the bracket. Then hold it up to the windshield.
Mounting Location Restrictions and Exemption
The figures below provide Lytx’s recommendations for mounting the ER on the vehicle windshield
that work within the guidelines set forth by the Federal Motor Carrier Safety Administration
(FMCSA)*. However, some states 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’s windshield or other locations in a vehicle

Connect Electrical Wiring
Connecting the electrical wiring consists of these main steps:
1. Review the electrical connection overview diagram and wiring suggestions.
2. Connect the three basic connections—the red, brown, and black wires on the Vehicle
Interconnect Cable.
3. Connect to the Vehicle J1939 Network Interface.
4. Route the ER cable.
Wiring Safety Warnings
WARNING: Only approved wire connection methods are recommended. Refer to the
vehicle manufacturer’s service manual to determine if Add-A-Circuit, Posi-Tap, sealing butt
connections, or OEM connections to open connection ports are approved. Never use plier tap
products such as scotch locks when installing the ER-SF1.
WARNING: Never wire the ER-SF1 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 must be fused. Failure to do so 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 two feet
or less. Do not overtighten any tie wraps.
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.

Wiring and Wire Termination Suggestions
WARNING: Failure to use proper wiring and wire terminations could lead to personal injury or
property damage. The following Wire Termination Suggestions should be followed to ensure
proper connections.
When installing the event recorder, there are several key rules to produce reliable electrical
connections:
1. Use ONLY 16- or 18-gauge automotive primary wire to connect to automotive circuits.
Specialty wire might be superior when used in its native environment, but not in the
automotive field (for example, Teflon wire is intended for high heat conditions, but should
never be used for connections of the event recorder in the vehicle).
2. For all connection methods, do not leave any exposed wire near the connector.
3. Do not use ScotchLoc, quick slide, or non-sealing butt connectors.
4. Posi-Tap connectors: Posi-Tap wiretap connectors may only be used inside the cab of the
vehicle and only for event recorder inputs. These include ignition, turn signals, and brake.
5. Crimp style connectors: All crimp style connectors must be the sealing type. Verify the
crimped connection is secure. Then heat up the connector to melt and seal it.
6. Fuse taps/Add-A-Circuits: If using a fuse tap (Add-A-Circuit), make sure that the hot leg of
the fuse receptacle connects to the leg of the fuse tap farthest from the connection wire. If
installed backwards, a fuse tap will compromise the original circuit. Never use a fuse tap on
an ECM, ECU, or control module circuit fuse.
ScotchLoc connectors
Quick Slide connectors
Do not tap wire as shown

Basic Event Recorder Electrical Connections
A minimum of three connections are required for the event recorder to function. These leads are
found on the Vehicle Interconnect Cable terminating at the female end of the Molex connector.
The red and black leads have 5-amp inline fuses; the brown lead has a 1-amp inline fuse.
Required Connections
1. Red wire: Provides primary power and must be connected to a continuous power source.
2. Brown wire: Functions as an ignition-sense, used by the event recorder to perform
functions such as activating the IR Illuminator when the vehicle ignition is switched on.
3. Black wire: Functions as ground.
Connect the RED WIRE to a 12V-24V power source that is ALWAYS ON
CAUTION: THIS IS A FUSED CONNECTION. DO NOT CUT OFF OR REMOVE THE FUSE
HOLDER.
The event recorder always remains “on.” This requires a 12V or 24V power source that is not
controlled by the key nor any other device or switch. Typically, this connection is made just after
the fuse box on the battery-side of any vehicle control modules. Use a voltmeter to make sure the
circuit provides continuous 12V or 24V power when the key is removed from the ignition and all
lights, devices and switches are off.
Ensure Sufficient Current Draw: If you’re tapping into an existing vehicle wire, make sure it can
handle the additional current draw of the event recorder. A wire that reads 12V on a voltmeter
may not necessarily be able to supply enough current to the existing circuit and the event

recorder. The gauge of wire being tapped into provides a good indication. A larger gauge wire is
often the best choice.
Connect the BROWN WIRE to a 12V-24V power source that is IGNITION-SWITCHED
CAUTION: THIS IS A FUSED CONNECTION. DO NOT CUT OFF OR REMOVE THE FUSE
HOLDER.
CAUTION: The brown wire to a 12V-24V power source that is ignition-switched is important to
ensure the event recorder can identify when the ignition is switched on and off and to control the
event recorder’s Hibernation mode. This connection requires a 12V or 24V power source that is
“on” either when the ignition is keyed all the way forward to the ON position and all the way back
to the OFF position. Failure to properly connect this fused connection may lead to vehicle battery
drain.
Common Mistake for Brown Wire Connections: This connection is often mistakenly made to a
modulated circuit—one that comes out of a computer control module running some subsystem in
the vehicle. This can give false ignition on/off signals. To avoid this, connect this wire to a circuit
that is on the battery side of any modules. Consult the vehicle wiring schematics or a local
authorized dealership to obtain this info.
Connect the BLACK WIRE to a Good Solid Vehicle Ground
CAUTION: THIS IS A FUSED CONNECTION. DO NOT CUT OFF OR REMOVE THE FUSE
HOLDER.
This connection is usually made via ring terminal to ground lug in the vehicle, supplied by the
vehicle manufacturer for aftermarket products. If one is not available, ensure that the connection
is solid to a metal portion of the vehicle which is directly grounded to the vehicle frame. Ensure
there is no corrosion or paint interfering with this connection.
Instructions for Basic Connections
1. Find a suitable location to make electrical connections (usually behind/under the
dashboard or power distribution center).
2. Connect the red, brown, and black wires from the Vehicle Interconnect Cable leads to the
vehicle as shown in the Electrical Connections Overview Diagram above. Be sure to follow
the parameters for each wire, detailed above.
Connect to the Vehicle J1939 Network Interface
Connectivity to the vehicle J1939 network is achieved with a coupling device called the CAN
Coupler. This device makes use of inductive technology to allow the ER to read the data on the
J1939 network without requiring any puncture, cut, or splice into the vehicle cabling.

Refer to the Electrical Connection Overview Diagram above for the following steps.
1. Connect the CAN Coupler to the Standard Power Cable.
2. Find a suitable location along the vehicle J1939 network backbone to insert the CAN
Coupler. The CAN Coupler MUST be installed in the vehicle cab. It cannot be exposed to
moisture or inclement weather conditions.
3. Untwist approximately 2 inches of the vehicle’s J1939 wires, which are always a green and
yellow twisted pair.
4. Insert the vehicle’s J1939 wires into the CAN Coupler with the yellow wire on the CAN-HI (Y)
side and the green wire on the CAN-LO (G) side. Ensure that the wires are secured in the
tabs provided and properly oriented.
5. Place the cap on the CAN Coupler.
Route the ER Cable
Note: You may need to remove the window and door trim to route the cable underneath. These
typically snap on and off using special clips. In vehicles with side and curtain airbags, the clips are
often one-time use and may need to be replaced after removal. Please refer to the vehicle service
manual for information.
1. Route the end of the ER cable from the adapter to the nearest door pillar. Route the cable
behind and underneath the dash until reaching the kick panel.
2. Starting from below the dash near the kick panel, route the end of the ER cable up the door
pillar underneath the vertical door/window trim to the top of the door pillar.
3. Route the ER cable across the top of the windshield under the window trim or headliner to
the ER device (see below).
WARNING: WHEN INSTALLING THE CABLE IN A VEHICLE WITH SIDE OR CURTAIN
AIRBAGS, BE CERTAIN THAT NEITHER THE CABLE NOR YOUR INSTALLATION ACTIVITIES
INTERFERES WITH ANY AIRBAG-RELATED MECHANISMS OR OTHERWISE RISKS AFFECTING
AIRBAG DEPLOYMENT.

Final Checks
After installation of the ER-SF1 but prior to any operation of the vehicle, check all vehicle system
lights, signals, and any other devices (such as electronic log devices systems or CB radios) to make
sure they are working properly. Minimum checks should include the following (consult the vehicle
manufacturer’s service manual for additional checks that must occur):
1. Constant power: Ensure the ER is powered when the ignition is off (12V to red wire).
2. Switched power: Confirm 12V to the brown wire when the ignition is on.
3. Ground: Ensure the black wire is connected to a solid grounding point in the vehicle with
no paint or rust.
4. Event creation: Turn the vehicle on and press either blue button on the ER. Confirm an
event is created by verifying the LED’s light up green from left to right, one by one.
5. Check-in: Hold either blue button on the ER down for ~6 seconds. The center LED on the
unit should go out and come back on. Release the button and confirm that the unit has
attempted to contact Lytx, Inc. During the check-in process, the LEDs will blink and then
turn solid green progressively from left to right.
a. If an LED turns red, the check-in has failed and must be attempted again. There will
be some instances where check in is not possible due to cellular coverage and the
installation is still okay. After check in or failure, the center green LED will come on.
6. Start the vehicle, cycle the transmission, and confirm there are no error codes/check
engine lights.
7. Test the other vehicle components on the power circuit of the ER-SF1 to confirm their
functionality, especially if the circuit is shared.
8. Verify and diagnose all active faults in the vehicle system, other devices, and the ER-SF1
prior to completing the installation.
9. Place the driver safety card and the warning card included with the ER packaging on the
driver’s seat.
10. Place the decal indicating the vehicle is equipped with a recording device on the driver’s
seat. The customer is responsible for visibly displaying this decal.
