Retain All Harnesses
NOTE: Store all the wiring harnesses supplied in the
kit — including any not used in this installation — with
the processor in the overhead compartment. Additional
systems that interact with the Autovue
®
LDW system, may
require these harnesses.
WIRING HARNESS ROUTING
See Figure 1. The 20 foot wiring harness can be routed via
either, or both, A-pillars. Routing may depend on where the
dash Enable/Disable switch will be located, and whether
speakers or seat-motors are to be used to alert the driver.
TURN SIGNAL CONNECTIONS
1. Test the turn signal system to verify that it is functioning
correctly.
2. Refertothewiringdiagramforthevehicletondwire
numbers for the left and right turn signals.
3. As necessary, remove the vehicle trim/panels to gain
access to the wiring looms where the left and right turn
signal wires are located.

4. Connect a test lamp, Voltmeter or Multimeter to each of
the turn signal positive wires and use the following tests
toconrmyouhavethecorrectwires.
Verifythatyound(forboththeleftand right wiring):
• When the turn signal is off, the test lamp should be
off (or 0v);
• When the turn signal is operating, the test lamp should
blink (or pulse 12v);
• When the service brake pedal is applied (with the turn
signal off), the lamp should be off (or 0v);
• When the parking brake pedal is engaged or
disengaged, (with the turn signal off), the lamp should
be off (or 0v); and
• When the headlights are switched on, (with the turn
signal off), the lamp should be off (or 0v).

5. Run the wiring harness to the location where the con-
nection will be made. Refer to the tags on the wires and
connect, by soldering or splicing, to their respective (left
or right) turn signal positive wires.
IGNITION, GROUND, AND BATTERY
CONNECTIONS
Three power connections must be made:
1. Ignition (Pin A9). Ignition power is required for the
processor, the Enable/Disable switch, and for kits
including seat motors, to the seat connector. Obtain
ignition power at a good 12 Volt accessory location:
typically at the fuse panel; or at the ignition switch.
CAUTION: The Ignition power MUST come from a suitable
vehicle circuit that is:
• Switched on and off by the ignition switch; and,
• Is protected by a fuse or circuit breaker with an
electrical current rating of no greater than 15 Amps
and no less than 5 Amps.
Connect Ignition power to both the harness red wire marked
IGNITION, and also to Pins 10 and 12 the Enable/Disable
switch. Use 18 gauge wire as needed.
2. Ground (Pin B9). Locate a suitable location on the
vehicle to make a good connection to chassis ground.
Potential locations are: the fuse box; the vehicle's
chassis;ortherewallnearthesteeringcolumn.Ifyou
selectthechassisorrewall—andinmakingtheground,
need to drill a hole — take care not damage, or interfere
with other vehicle components.
• Connect ground to the harness black wire marked
GROUND, and also to Pin 2 of the Enable/Disable
switch. Use 18 gauge wire as needed.
3. To the Battery (Pin A11). The battery connection must
be made at a location where 12 Volt battery voltage
is constantly present, regardless of the ignition state.
This is essential for full functionality of the optional data
recording features.
Make sure that the battery connection is stable by

at the battery connection regardless of the ignition switch
position.
