If using a vehicle harness with a diagnostic port connector, some or all of these functions may be provided
through that connection. In these cases, some or all the wires shown above will already be installed to the
diagnostic port connector.
Connect the Vehicle Harness power wire (red) to the vehicle power bus (11-36V).
o
The power source must be capable of providing 3 amps
o
If it is desired that the Road-iQ VideoData Server be operational when the vehicle is shut off, the power
wire should be connected to a constant power source (one that is not switched with the vehicle’s
ignition)
Connect the Vehicle Harness ground wires (2X black) to a chassis ground.
o
Grounding best practice.
Connect the Vehicle Harness ACC wire (yellow w/ white stripe) to a power source that is switched ON when the
unit should be operational. By default, the ACC line acts to signal the VideoData Server to indicate when the unit
should be operating. The ACC power source can be:
o
Switched with vehicle ignition, so that the Road-iQ VideoData Server operates only when the vehicle is
operating.
o
Constant power through a toggle switch, allowing the end user to manually choose when the Road-iQ
VideoData Server will operate
Note: there is an additional ACC line included in the optional GPIO harness. This line, also yellow with a
white stripe, can be used in place of the Vehicle Harness ACC line if it aids in the routing of the
harnesses.

The CAN-bus can be accessed in a number of ways:
o
Through a diagnostic port connector installed on the Vehicle Harness
o
Using a Y-adapter at an existing CAN connection to add the server to the network
o
Splicing directly into the network wires
If you will be using a diagnostic port connector (OBDII, J1939, and/or RV-C):
